Understanding the nucleon structure is currently one of the main challenges encountered in nuclear physics. The present work represents a contribution to the study of the nucleon structure and deals, in particular, with the study of the role of strange quarks in the nucleon. The latter can be investigated by determing the strange quark distribution in the nucleon as well as the contribution of the spins of strange quarks to the nucleon spin ($\Delta s$). This work first presents a measurement of $\Delta s$ performed via Deeply Inelastic Scattering of a muon beam off polarized proton and deuterium targets. The result is found to be strongly dependent on the quark fragmentation functions into hadrons (FFs), which define the probability that a quark of a given flavour fragments into a final state hadron. The FFs are poorly known, in particular, the FF of strange quark into kaons, which play an important role in the determination of $\Delta s$. In deep inelastic scattering process, the access to the FFs is provided by the hadron multiplicities which, in turn, define the average number of hadrons produced per DIS event. Pion and kaon multiplicities have been extracted versus different kinematic variables, using DIS data collected by deeply inelastic scattering of a $160$ GeV muons off a deuterium target. A first LO extraction of the fragmentation functions has then been performed using the measured pion and kaon multiplicities.

E864 was designed as a high sensitivity search for strange quark matter produced in heavy ion collisions at the AGS accelerator at Brookhaven National Laboratory. In this thesis, we analyze data taken at the -0.75T field setting of the experiment, which is optimal for finding negatively charged strangelet candidates, from Au + Pt collisions at 11.6 GeV/c per nucleon. A measurement of the antiproton invariant multiplicities is made and is in reasonable agreement with previous E864 antiproton measurements. No conclusive strangelet candidates are found, and upper limits are set on the production of charge -1 and charge -2 strangelets of approximately 1 x 10- 8 and 4 x 10- 9 per 10% central collision respectively. These represent world's best limits to date.

The goal of the G0 experiment is to determine the contribution of the strange quarks in the quark-antiquark sea to the structure of the nucleon. to this end, the experiment measured parity-violating asymmetries from elastic electron-proton scattering from 0.12 ≤ Q2 ≤ 1.0 (GeV/ c)2 at Thomas Jefferson National Accelerator Facility. These asymmetries come from the interference of the electromagnetic and neutral weak interactions, and are sensitive to the strange quark contributions in the proton. The results from the forward angle measurement, the linear combination of the strange electric and magnetic form factors GsE + etaGsM, suggest possible non-zero, Q 2 dependent, strange quark contributions and provide new information to understand the magnitude of the contributions. This dissertation presents the analysis and results of the forward-angle measurement.;In addition, the G0 experiment measured the beam-normal single-spin asymmetry in the elastic scattering of transversely polarized 3 GeV electrons from unpolarized protons at Q2 = 0.15, 0.25 (GeV/c) 2 as part of the forward-angle measurement. The transverse asymmetry provides a direct probe of the imaginary component of the two-photon exchange amplitude, the complete description of which is important in the interpretation of data from precision electron-scattering experiments. The results of the measurement indicate that calculations using solely the elastic nucleon intermediate state are insufficient and generally agree with calculations that include significant inelastic hadronic intermediate state contributions. This dissertation presents the analysis and results of this measurement.

I present a calculation of the leading strange quark-connected contribution to the anomalous magnetic moment of the muon, α_μ^(2)had,s , using lattice QCD. The calculation is performed on two ensembles with lattice extents of 48³ x 96 and 64³ x 128 with associated inverse lattice spacings of 1:730(4)GeV and 2:359(7)GeV. These were generated with the Iwasaki gauge action and 2+1 dynamical quark flavours, which, along with the valence quarks, are represented on the lattice using the Möbius domain wall fermion action. To account for a slight mistuning in the strange quark mass I use both unitary and partially quenched measurements on each ensemble. I principally use the hybrid method to determine α_μ^(2)had,s , and I implement several variations of the method in order to quantify a systematic error associated with the selection of any particular variation. In addition, I use a Fourier transformation to compute the hadronic vacuum polarisation (HVP) at momenta not accessible on the lattice, a technique called sine cardinal interpolation (SCI). All these techniques produce results that are highly consistent with one another. Finite volume corrections are expected to be negligible, since G-parity prevents the strange vector current from coupling to pions in the isospin limit. My final result is α_μ^(2)had,s = 53.1(9)(⁺¹_-3) x 10^-10 where the first error is statistical and the second is systematic. The total error on this result (roughly 2%) is dominated by the statistical uncertainty, which suggests that the methods used here to compute α_μ^(2)had,s in the case of the strange HVP are robust.

The experiments discussed in this thesis exploit parity violation in elastic electron proton scattering in order to measure properties of the nucleon. Both experiments make use of the high quality, highly polarized electron beam available at Thomas Jefferson National Accelerator Facility. Qweak will measure the weak mixing angle, sin²θ_W, via a measurement of the weak charge of the proton, at a four-momentum transfer, Q²~0.026 GeV²/c². The precision of this measurement gives Qweak access to new physics at the scale of 2.3 TeV, making it a test of the standard model. The G0 experimental program provides the fully separated contributions of the strange quark to the charge and magnetization distributions of the nucleon at two different values of four-momentum transfer, Q² ~ 0.22 and 0.63 GeV²/c². The measurement of the strange quark content of the proton in the G0 experimental program and other parity-violating electron scattering experiments provides a measurement of the hadronic contribution to the asymmetry in Qweak. In addition, G0 was able to measure the parity-conserving beam normal single spin asymmetries that provide a measurement of the imaginary part of two photon exchange. The measurement of this asymmetry is necessary to understand the systematic contribution to measurements of parity-violating asymmetries, but it is also an important physics result. Recent theoretical work has shown that higher order radiative effects, such as two photon exchange, may be able to explain discrepancies between experiments which measure the ratio of the electric and magnetic form factors of the proton. The measurement of the transverse or beam normal single spin asymmetries provides a benchmark for theories that estimate the size of radiative corrections that are important for precision electroweak scattering experiments such as those described in this thesis. The results of the measurement of the transverse asymmetries at backward angles in G0 are presented at the two values of Q² ~ 0.22 and 0.63 GeV²/c² for hydrogen. Results for deuterium, which can provide the first measurements of the beam normal single spin asymmetries on the neutron, are also presented.

Quark–gluon plasma is a state of matter existing under extreme energy densities and temperatures where quarks and gluons are deconfined. This hot and dense strongly interacting matter can be created in ultra-relativistic heavy-ion collisions. Measurements of spectra of identified particles produced in jets represent a major tool for studying properties of the plasma created in the collisions and for understanding the interplay of various mechanisms which contribute to the particle production in this medium. In this thesis, we present the measurement of the transverse-momentum spectra of Λ baryons and K0S mesons produced in charged jets in central Pb–Pb collisions at the centre-of-mass energy sqrt(sNN) = 2.76 TeV, measured with ALICE at the LHC. The results of the analysis are used to discuss the origin of the enhancement of the baryon-to-meson ratio observed for the inclusive production of light-flavour particles in ultra-relativistic heavy-ion collisions

The parity violating weak decay of hyperons offers a valuable means of measuring their polarization, providing insight into the production of strange quarks and the matter they compose. Jefferson Lab’s CLAS collaboration has utilized this property of hyperons, publishing the most precise polarization measurements for the Λ and Σ in both photoproduction and electroproduction to date. In contrast, cascades, which contain two strange quarks, can only be produced through indirect processes and as a result, exhibit low cross sections thus remaining experimentally elusive. At present, there are two aspects in cascade physics where progress has been minimal: characterizing their production mechanism, which lacks theoretical and experimental developments, and observation of the numerous excited cascade resonances that are required to exist by flavor SU(3)F symmetry. However, CLAS data were collected in 2008 with a luminosity of 68 pb−1 using a circularly polarized photon beam with energies up to 5.45 GeV, incident on a liquid hydrogen target. This dataset is, at present, the world’s largest for meson photoproduction in its energy range and provides a unique opportunity to study cascade physics with polarization measurements. The current analysis explores hyperon production through the γp → K+K+Ξ− reaction by providing the first ever determination of spin observables P, Cx and Cz for the cascade. Three of our primary goals are to test the only cascade photoproduction model in existence, examine the underlying processes that give rise to hyperon polarization, and to stimulate future theoretical developments while providing constraints for their parameters. Our research is part of a broader program to understand the production of strange quarks and hadrons with strangeness. The remainder of this document discusses the motivation behind such research, the method of data collection, details of their analysis, and the significance of our results.

Quantum Chromodynamics (QCD) is the fundamental theory for the strong interaction in high energy physics, and lattice QCD (formulating QCD on a discrete space-time lattice) is the most viable way to solve QCD nonperturbatively from the first principles. In this thesis, we perform an exploratory study of the mass spectrum of mesons and baryons in lattice QCD with $N_f = 2 $ optimal domain-wall quarks. Even though the pion mass of these gauge ensembles are unphysical, about 300 MeV, the mass spectrum of the mesons and baryons containing charm and strange quarks seem to be in good agreement with the high energy experimental values.

The role of strange quarks in generating the structure of the nucleon provides a key testing-ground for our understanding of Quantum Chromodynamics (QCD). Because the nucleon has zero net strangeness, strange observables give tremendous insight into the nature of the vacuum; they can only arise through quantum fluctuations in which strange-antistrange quark pairs are generated. Strange observables are also relevant to searches for physics beyond the Standard Model; the role of the strange quark in generating the nucleon mass-encoded in the strange sigma term-is essential information for the interpretation of dark matter direct-detection experiments. For these reasons, strangeness in the nucleon is currently a particular focus of the nuclear physics community. We use the numerical lattice gauge theory approach to QCD, and the chiral perturbation theory formalism, to build a clear picture of the role of strange quarks in various nucleon-structure observables. A detailed analysis of the octet baryon masses provides precise new values of the nucleon sigma terms. By combining experimental and lattice input, we deduce the strange electromagnetic form factors of the nucleon over a far larger range of momentum-scales than is accessible experimentally. Our calculation of the strange magnetic moment is an order of magnitude more precise than the closest experimental result. Until now, the dominant uncertainty in experimental determinations of the strange proton form factors has come from a lack of knowledge about the size of charge symmetry violation (CSV) in these quantities. CSV effects quantify the breaking of the approximate SU(2)-flavour symmetry of the up and down quarks. As well as their relevance to experimental determinations of nucleon strangeness, the precise knowledge of CSV observables has, with increasing experimental precision, become essential to the interpretation of many searches for physics beyond the Standard Model. We develop a formalism for the calculation of CSV observables from isospin-averaged 2 + 1-flavour lattice QCD simulations. Applying this formalism to a comprehensive lattice-based study of the electric and magnetic Sachs form factors of the baryon octet reveals that the CSV form factors are an order of magnitude smaller than suggested by previous work. This calculation opens the door for new, precise, experimental measurements of the strange nucleon form factors. We also investigate the proton-neutron mass difference and quantify the long-neglected CSV effects in the low Mellin moments of the spindependent and spin-independent parton distribution functions. This analysis improves the interpretation of neutrino-nucleus deep inelastic scattering experiments.

This thesis reports on two experiments conducted by the HAPPEx (Hall A Proton Parity Experiment) collaboration at the Thomas Jefferson National Accelerator Facility. For both, the weak neutral current interaction (WNC, mediated by the Z0 boson) is used to probe novel properties of hadronic targets. The WNC interaction amplitude is extracted by measuring the parity-violating asymmetry in the elastic scattering of longitudinally polarized electrons off unpolarized target hadrons. HAPPEx-III, conducted in the Fall of 2009, used a liquid hydrogen target at a momentum transfer of Q2 = 0.62 GeV2. The measured asymmetry was used to set new constraints on the contribution of strange quark form factors ([special characters omitted]) to the nucleon electromagnetic form factors. A value of APV = −23.803 ± 0.778 (stat) ± 0.359 (syst) ppm resulted in [special characters omitted] = 0.003 ± 0.010 (stat) ± 0.004 (syst) ± 0.009 (FF). PREx, conducted in the Spring of 2010, used a polarized electron beam on a 208Pb target at a momentum transfer of Q 2 = 0.009 GeV2. This parity-violating asymmetry can be used to obtain a clean measurement of the root-mean-square radius of the neutrons in the 208Pb nucleus. The Z 0 boson couples mainly to neutrons; the neutron weak charge is much larger than that of the proton. The value of this asymmetry is at the sub-ppm level and has a projected experimental fractional precision of 3%. We will describe the accelerator setup used to set controls on helicity-correlated beam asymmetries and the analysis methods for finding the raw asymmetry for HAPPEx-III. We will also discuss in some detail the preparations to meet the experimental challenges associated with measuring such a small asymmetry with the degree of precision required for PREx.

【Abstract】 The neutron star or strange quark star can be described by the differential equations including the mass equation, the hydrostatic equilibrium equation (TOV), and the equation of state (EOS). In this thesis, we try to describe the rotation of stars and to obtain the structure of a neutron star or strange quark star with the modified differential equations. Through the numerical analysis we compare the different Chandrasekhar limits between dense stars with rotations and without. Our major findings include： (1)The maximum stellar mass (Chandrasekhar limit) for rotating strange stars with angular velocity W0＝5×103 sec－1 is larger than the one without rotation by about 4.63﹪while, for neutron stars, the rate of increase is 4.55﹪. (2)The role played by the differential rotation W1 could in principle be as important as the average rotation W0 if W1~W0.

Dissertação de Mestrado em Física apresentada à Faculdade de Ciências e Tecnologia
Nesta tese, a sensibilidade do detector ATLAS para a medida da fração de decaimento do quark top t → sW é apresentada. Os dados analisados foram recolhidos pelo detetor ATLAS durante os primeiros dois anos da Run II (2015-2016), em colisões de protão-protão no Grande Colisionador de Hadrões (LHC), com uma energia de centro de massa de s = √13 TeV, correspondendo a uma luminosidade integrada de 36.2 fb−1 , escalada para 150 fb−1 . Como sinal eventos de decaimento de pares de quarks top são usados, onde um dos quarks decai pelo canal t → sW e o outro pelo decaimento principal do quark top, t → bW . Nos eventos escolhidos, ambos os bosões W decaem leptonicamente, com um a decair para um electrão e o outro para um muão, de cargas opostas. A fração de decaimento medida é BR(t → sW ) = 0.00162 ± 0.00006 (stat) ±0.00006 (sist). Foi também medida a fração de decaimento de t → bW , tendo sido obtido BR(t → bW ) = 0.9983 ± 0.0007 (stat) ± 0.0012 (sist). Este resultado foi obtido com uma significância do sinal de 6.0 ± 0.9 (apenas incerteza estatística). Isto leva a conclusão que uma medida pode ser possível com os dados da Run II completa. . . . .
In this thesis, the ATLAS detector sensitivity for the measurement of the top quark decay t → sW branching ratio is presented. Data collected by the ATLAS detector during the first two years of Run II (2015-2016) from proton-proton collisions at the Large Hadron Collider (LHC), with a center-of-mass energy of s = √13 TeV, corresponding to an integrated luminosity of 36.2 fb−1 , scaled to 150 fb−1 , are analysed. As signal, top-quark pair-decay events are used, where one of the quark decays through the t → sW channel and the other through the main decay of the top quark, t → bW . In the events chosen, both W bosons decay leptonically, with one decaying to an electron and another to a muon, of opposite charges. The branching ratio estimated is BR(t → sW ) = 0.00162 ± 0.00013 (stat) ± 0.00014 (syst). Additionally, the branching ratio of t → bW is estimated to be BR(t → bW ) = 0.9983 ± 0.0060 (stat) ±0.0006 (syst). This result was obtained with a signal significance of 6.0 ± 0.9 (statistical uncertainty only). This leads to the conclusion that a measurement might be possible with the full Run II dataset. . . .. .

In this thesis, we investigated the strange quark matter (SQM) composed of the spin-up and spin-down; up, down and strange quarks at finite temperature in the presence of the strong magnetic field using the MIT bag model. We computed the total free energy of the spin polarized SQM at finite temperature in the presence of the strong magnetic field. We found that the free energy gets a minimum at a particular value of the spin polarization parameter showing a meta-stable state. The calculation shown that by increasing temperature, the equation of state of spin polarized SQM becomes stiffer. Also, using the general relativistic TOV equation, we studied the structure of the spin polarized strange quark star (SQS). We calculated the maximum mass and corresponding radius of spin polarized SQS at different temperatures and magnetic fields. We shown that the gravitational mass of spin polarized SQS rapidly increases by increasing the central energy density. We also indicated that the mass and the radius of the spin polarized SQS decreases by increasing both temperature and magnetic field.

v anglickém jazyce: This thesis mainly analyzes the five-part novel Gargantua and Pantagruel written by the French author Francois Rabelais. Emphasis is based particularly on an inclusion of Rabelais's work in historical and literary context of the period of transformation between medieval and Renaissance society. More specifically, it deals with the author's humanist opinion and his critique of contemporary society, which is the main line of the work itself. The aim of our thesis is especially an attempt to outline the various possible meanings of the terms « road or path » and « stranger » in Rabelais's work and explain the role of these thematic concepts in the author's concept of criticism of society.
