Abstract:
In this essay, we examine the response of an Unruh–DeWitt (UD) detector (a quantum two-level system) to a gravitational wave background. The spectrum of the UD detector is of the same form as some scattering processes or three body decays such as muon-electron scattering or muon decay. Based on this similarity, we propose that the UD detector response implies a “decay” or attenuation of gravitons, [Formula: see text], into photons, [Formula: see text], via [Formula: see text] or [Formula: see text]. Over large distances such a decay/attenuation may have consequences in regard to the detection of gravitational waves.

Abstract:
The Mu2e experiment at Fermilab searches for the charged-lepton flavor violating neutrino-less conversion of a negative muon into an electron in the field of an aluminum nucleus. The dynamics of such a process is well modelled by a two-body decay, resulting in a mono-energetic electron with an energy slightly below the muon rest mass. If no events are observed, in three years of running Mu2e will improve the current limit by four orders of magnitude. Such a charged lepton flavor-violating reaction probes new physics at a scale inaccessible with direct searches at either present or planned high energy colliders. The experiment both complements and extends the current search for muon decay to electron-photon at MEG and searches for new physics at the LHC. This paper focuses on the physics motivation, the design and the status of the experiment.

Abstract:
Abstract In several refractory body-centred cubic metals (α-Fe, V, Nb, Ta) the binding energy of positrons (e+) trapped in vacancies is too small to permit accurate determinations of the enthalpy of formation of monovacancies, H 1V F , $ H_{{\rm{1V}}}^{\rm{F}},$ by high-temperature positron annihilation. Owing to their larger mass, trapped positive muons (μ+) and π-mesons (π+) are much more firmly bound to vacancies. It is argued that the lattice steering (channelling or blocking) of their charged decay products (e+ or μ+) allows us to obtain accurate H 1V F $ H_{{\rm{1V}}}^{\rm{F}}$ values of the refractory bcc metals. In ferromagnets with high Curie temperatures T C, such as α-Fe, Co, and FeCo alloys, H 1V F $ H_{{\rm{1V}}}^{\rm{F}}$ may also be deduced from muon spin rotation (μ+SR) measurements. However, in Fe and Co this approach is limited by the strong sensitivity of the spontaneous magnetization against temperature fluctuations near T C. The reduction of this sensitivity in the so-called asymptotic critical regime by applying sufficiently strong external magnetic fields is investigated on the basis of the Arrott– Noakes equation. A method for determining the critical amplitudes occurring in this equation is proposed. In disordered Fe1–xCox alloys (0.2 ≤ x ≤ 0.75) the Curie temperatures are sufficiently high for the spontaneous magnetization in the bcc phase not to be critically affected by temperature fluctuations, hence these alloys are well suited for μ+SR investigations of thermal vacancies. From an analysis of the available positron-annihilation and self-diffusion data the vacancy migration enthalpy in disordered Fe0.5Co0.5 is found to be (1.1 ± 0.2) eV, in good agreement with quenching data and with the value established for α-Fe.

Abstract:
John David (“Dave”) Jackson, a Canadian-born theoretical physicist, contributed significantly to particle, nuclear, and atomic physics. He is best known, however, for his text Classical Electrodynamics, which has been a fixture in physics graduate education around the world for more than 50 years. It is generally referred to simply as “Jackson.” This textbook, which has inspired fear and wonder alike in generations of students, clearly reflects the author's fascination with physical phenomena, his renowned mathematical dexterity, and his appreciation of the elegance of physical laws. Jackson's major contributions to research included the theory of muon-catalyzed fusion; the analysis, with Kurt Gottfried, of angular distributions in quasi-two-body elementary particle collisions; and the elucidation of charmonium-state decays. Jackson influenced the development of physics research throughout the United States as well as internationally—particularly through his work on the nascent Superconducting Super Collider. An active promoter of civil liberties and human rights, he was one of the leaders of the efforts to free Andrei Sakharov, Yuri Orlov, and Anatoly Shcharansky from Soviet imprisonment.

Abstract:
The most general form of Hamiltonian for the muon decay is presented. We assume that it arises as a result of the exchange of intermediate bosons with a momentum q and naturally should depend on this momentum. That allows us to introduce two additional coupling constants for the tensor interactions which give rise to new parameters in the energy spectrum of positrons. The experimental consequences of such a generalization are discussed.

Taking into account the two-gluon condensate corrections, the transition form factors of the semileptonicχc2→Dsl-ν(l=e,μ)decay channel are calculated via three-point QCD sum rules. These form factors are used to estimate the decay width of the transition under consideration in both electron and muon channels. The obtained results can be used both in direct search for such decay channels at charm factories and in analysis of theBcmeson decay at LHC.

Full text
Abstract:
This thesis describes a study of the muon selection for the search of the Standard Model Higgs boson decay to two muons with the CMS detector at LHC. Data collected during the 2017 run have been analyzed, corresponding to an integrated luminosity of 41.6 1/fb. Three strategies, built upon different selection criteria and muon momentum requirements, are tested. The agreement between data and Monte Carlo distributions for the most relevant kinematic variables is found to be good. The efficiency of muon identification and isolation has been measured with real data, and corrections to the Monte Carlo estimates (so-called “scale factors”) have been determined as a function of muon transverse momentum and pseudorapidity. The statistical significance obtained by the three selections has been estimated using simulated signal and background samples, in order to establish the best compromise between efficiency and purity. The so-called \textit{medium} muon selection with loose isolation cuts and a transverse momentum cut at 10 GeV is found to achieve the best significance.

Abstract:
A search for B decays to quasi two-body charmless final states involving a pseudoscalar η′ meson recoiling against a K∗ vector meson is described. This thesis primarily describes the analysis of two of the six possible decay channels, with the other four channels necessarily included as the subdecay modes are combined to give an overall branching fraction measurement. The method of analysis is a multivariate maximum likelihood fit for each subdecay channel. The likelihood curves for both modes are then combined, firstly with two other charged modes to yield an overall charged result, and finally the four charged modes are combined with two neutral modes to give an overall branching fraction and significance for the decay channel B → η′K∗. All results use the full Run 1 to Run 4 datasets, comprising 210.5 fb−1 of data, equivalent to 232 million BB pairs, gathered by the BABAR detector at Stanford Linear Accelerator Center in Menlo Park, California. The measured branching fractions and upper limits at 90% confidence limit (CL) are: B(B+ → η′ηππK∗+ K+π0) < 9.5 × 10−6B(B+ → η′ργK∗+ K+π0) < 22 × 10−6.The four-mode combined fit determined the branching fraction for the decay B+ → η′K∗+: B(B+ → η′K∗+) < 7.9 × 10−6. The six-mode combined fit determined the branching fraction for the decay B → η′K∗: B(B → η′K∗) = (4.1 ± 1.0 ± 0.5) × 10−6 at a significance of 5.6 standard deviations.

Abstract:
Decays of neutral D mesons to final states containing K + π's could provide evidence for CP-violation from a source not accounted for in the Standard Model. Due to the interference between Cabibbo-favored and Cabibbo-suppressed transitions, a decay rate asymmetry of D0 → K0S π0 compared to D0 → K0Lπ0 has been predicted to be non-zero. If New Physics interferes in doubly Cabibbo-suppressed D decays, the measurement of this asymmetry would differ from the predicted value and may provide evidence for CP-violation beyond the CKM mechanism. I present an analysis method to measure this branching fraction asymmetry, R(D0) ≡ B(D0→K0S π0)−B(D0→K0L π0)/(B(D0→K0Sπ0)+B(D0→K0Lπ0)), utilizing e+e− → cc events in the Belle dataset.

The Universe appears to be made almost entirely of matter rather than antimatter; however, matter and antimatter should have been created in equal amounts in the Big Bang. We do not know exactly why we observe so much more matter as compared to antimatter. The Standard Model (SM) of particle physics accounts for some of the asymmetry through Charge-Parity (CP) symmetry violation, which explains how particles behave differently than their corresponding antiparticles. In the current state of the SM, some CP-violation is allowed in decays via the weak force, but the theory does not account for enough CP violation to explain the amount of matter-antimatter asymmetry observed in the Universe. Decays of a D meson to a kaon (K meson) plus one or more pions (π mesons) via a new mechanism beyond the weak force could provide evidence of a new source of CP-violation. In this analysis, I present a method for analyzing the decays of neutral D mesons to a neutral kaon and a neutral pion in the Belle dataset to test the SM.

AbstractThis chapter illustrates the general method to calculate the shape of the angular distribution for any considered two-body decay, and surveys examples for different kinds of initial particles, with integer or halfinteger J. We describe the dependences of the angular distribution shapes on J, Jz and the identity of the decay products, as well as the physical domains of the observable parameters. We also discuss how the measurement of the decay angular distribution can lead to the determination of J for an unidentified decaying particle.

Abstract:
Abstract Leifeng Pagoda originated at the bequest of Wuyue King Qian Chu, who created reliquaries and printed copies of The Precious Chest Seal Dhārani Sūtra and installed these in pagodas. The creation of reliquaries and printed copies of the Sūtra follows the model of King Aśoka, who allegedly erected eighty-four thousand stūpa reliquaries to house Śākyamuni’s remains, including his physical remains as well as his teachings. The contents of The Precious Chest Seal Dhārani Sūtra exhibit the miraculous powers extended to all who construct stūpas and copy the Precious Chest Seal Dhārani Sūtra. In later centuries, the Leifeng Pagoda became associated with the legend of the White Snake, the culmination of a body of snake-inspired lore; stories of young men becoming involved with snake-women have a long tradition in Chinese literature. After falling into disuse and decay, the Pagoda collapsed in 1924 and was eventually resurrected in 2002.

Abstract:
Meanwhile, adaptations of Oscar Wilde’s queer classic The Picture of Dorian Gray extend and elaborate on explorations of the double by explicitly invoking histories of sexual representation in connection to the sensual qualities of technology and nostalgia. In chapter 5, “`Strange Legacies of Thought and Passion’: Technologies of the Flesh and the Queering Effect of Dorian Gray,” I continue my analysis of the relationship between pornography, legacy, doubles, and technology through a close examination of two films based on Wilde’s novel: Take Off (1976) and Gluttony (2001). More than any other text, Dorian Gray engenders pornographic engagement with erotic legacy and the role of technology in the erotics of representation. Like Wilde’s novel, these films interrogate beauty and mortality, haunted at the margins by Wilde’s tragic fate and the HIV/AIDS pandemic. Drawing on Wilde’s magic portrait as a predecessor, Take Off and Gluttony ruminate on mortality and relate it to the sensual, tactile qualities of evolving, mobile visual technologies and the role these technologies play in sexual subjectivity. Pornographic film, Weston and West suggest, is the inheritor to Wilde’s portrait. Both films draw on Wilde’s tale in order to address the media on which the self is captured, the shifting technologies used to exhibit this self, and the relationship of technology and media to the corporeal body. Through their reimagining of histories of Hollywood and pornographic film, respectively, Take Off and Gluttony signal the affective relationship between technology, pornography, decay, and popular culture, tracing a hardcore sexual history of the self that constitutes a sexual lineage.

The simulations indicated the strong influence of the bilge radius in the damping coefficient of the FPSO section. Interesting results were obtained regarding the time series of the displacement of the body and vortex shedding around the bilge keel.

Abstract:
In this study the hydraulic-thermal developing laminar swirling pipe flow is investigated numerically. Solution is based on the integral boundary layer method Uniform and solid body rotation distributions are considered for the axial and tangential velocities at the entry, respectively. Due to wall stress, viscous region is assumed to contain two boundary layers for axial and tangential velocities. Outside of the boundary layers’ edge the flow pattern is considered to remains uniform in axial direction and forced vortex in tangential direction. Inside boundary layers parabolic velocity and temperature profiles were considered for axi-symmetric flow pattern with uniform heat flux (UHF) condition on the pipe wall. Making use of the fourth-order Runge-Kutta scheme, the numerical solution of the governing differential equations is obtained. As an alternative solution, a CFD analysis based on the finite-volume method, has been done. Finally validity of the numerical results was checked with those obtained by CFD.

Full text
Abstract:
We study the non-linear decay motion of a 2D plate experimentally and analytically. The plate was hinged to the bottom of a wave flume and was positioned at a certain initial angle. The restoring force on the plate was derived from two horizontal pre-tensioned springs. To maintain the system characteristics linear, the springs were selected to allow a maximum 18 degrees of rotation for the plate. The position, velocity and the acceleration of the plate were retrieved from the load cells attached to the springs. The plate was released from its initial position at t = 0 and allowed to oscillate. The free-surface elevation was captured using a high frame per second (200 fps) digital camera. In addition, two wave probes on either side of the plate were installed. It was observed that the high stiffness of the springs produced a mild impact to the water that caused a relatively large water run-up and water jet. This event, consequently, made the decay motion very non-linear. A formulation based on the linear theory was developed to help with the understanding and interpreting the physics of the problem. The presented experiment aims to benchmark various numerical techniques such as Smoothed Particle Hydrodynamics (SPH) that intend to simulate free-surface and water impact problems. Although the setup did not model a green water incident, most of the features in the problem, like initial water impact, run up and water jet resemble the physics of green water. In the designed experiment, not only body 3D effects were minimum, but also the system characteristics were linear. Moreover, in contrast to the dam break experiments, perfect initial conditions were achieved. Therefore, the effects of the flow nonlinearities such as the plate impact to the water, water run up-down and water jet were studied without interference of the body nonlinearities. The impact of these effects on the damping and the added mass were highlighted.

Full text
Abstract:
The current work is the first in a series of investigations to develop a method for high-temperature thermometry of gaseous flows using thermocouple pairs with disparate convective properties to infer the contribution of radiation. Two thermocouples of deliberately dissimilar bead geometry are placed side-by-side in a flow while the two beads are heated by surface radiation. Their dissimilar responses to radiation cause a predictable divergence between the two temperature measurements. The current approach improves upon others found in literature owing to its in-situ measurement for convection coefficients rather than dependence on empirical estimation. Each bead is deliberately overheated, and the time constant of the thermal decay back to equilibrium indicates the intensity of convection. Here, we perform this measurement in air while varying velocity, duration of overheat, and intensity of overheat. We compare the calculated temperature correction against the known air temperature. Heat transfer through the probe wires to the ceramic probe support was found to have a strong effect on the correction, although corrected values were always closer to the actual gas temperature than the original uncorrected value. In conditions of mild radiation loading, the effect was sufficiently symmetric between the two beads to allow effective correction. All measurements indicated that if additional information about the probe body temperature was collected in addition to the thermocouple measurements, the correction could be improved significantly.

Abstract:
In this study, in order to evaluate hydrodynamic behaviors of the hybrid floating body with cylinders, experimental studies were carried out. At first, two small-scale models of pontoon and hybrid with scale factor 1:75 were fabricated and tested under the wave loadings. Based on the measured data, hydrodynamic motions of the pitch, surge, drift force, and free decay motions were evaluated and compared with each other. As the result of small-scale test, it was found that the pitch motion is more sensitive to the wave period than the surge and drift motions. Whereas the pitch motion increased by increasing of the wave period, the surge and drift motion presented a small variance according to the increasing of the wave period for the both models of pontoon and hybrid. Also, it was found that the hybrid floating body significantly influenced on the hydrodynamic motions under the wave loadings. The pitch motion reduced significantly for the all wave period cases. The surge and drift motion reduced over the wave period of 0.982sec. Damping properties of hybrid model indicated more favorable in terms of logarithmic decrement and damping ratio because of the shape effects. Therefore, it was expected that the hybrid model of this study contribute to improve serviceability and safety of floating body as decreasing hydrodynamic motions.
