Повний текст джерелаOne of the final steps in simulations of lattice Quantum Chromodynamics (QCD) or lattice pure gauge theory is the continuum extrapolation to extract the actual continuum physics. This extrapolation relies heavily on assumptions regarding the asymptotic dependence on the lattice spacing, which introduces an inherent systematic uncertainty to the continuum limit. In classical field theories the asymptotic form is a power series in the lattice spacing, where the leading power depends on the chosen lattice discretisation. The quantum nature of lattice QCD and lattice pure gauge theory spoils this behaviour. For asymptotically free theories like lattice QCD the integer powers in the lattice spacing are multiplied by an additional power in the running coupling. The leading powers in the coupling can be determined from the anomalous dimensions of higher dimensional operators, which form a minimal basis of a Symanzik Effective theory. The scope of this thesis is to compute the leading powers in the coupling for the Wilson or Ginsparg-Wilson (GW) action relevant for spectral quantities like hadron masses. The lower bound of these powers is close to zero for lattice QCD with Wilson or GW quarks such that no problems from a reduced convergence towards the continuum limit are to be expected. However the spectrum of leading powers is very dense. The operator of the minimal basis with dominant contributions to the lattice artifacts is thus hard to determine and complicated interplay of the contributions from the various operators is possible. Now the leading corrections from lattice actions with Wilson or GW quarks to the classical power in the lattice spacing are known and should be used when performing the continuum extrapolation both through explicit use in the fit ansatz and as an orientation to estimate the systematic uncertainty inherent to the continuum limit.

Повний текст джерелаThe formulation of chiral perturbation theory (ChPT) for lattice Quantum Chromodynamics (QCD) is reviewed. We start with brief summaries of ChPT for continuum QCD as well as the Symanzik effective theory for lattice QCD. We then review the formulation of ChPT for lattice QCD. After an additional chapter on partial quenching and mixed action theories various concrete applications are discussed: Wilson ChPT, staggered ChPT and Wilson ChPT with a twisted mass term. The remaining chapters deal with the epsilon regime with Wilson fermions and selected results in mixed action ChPT. Finally, the formulation of heavy vector meson ChPT with Wilson fermions is discussed.

Повний текст джерелаMass is one of the most fundamental properties of matter. Understanding its origin has long been a central topic in physics. According to modern particle and nuclear physics, the key to this issue is to understand the origin of nucleon (lowest-lying baryon) masses from the nonperturbative strong interaction. With the development of computing technologies, lattice Quantum Chromodynamics simulations provide great opportunities to understand the origin of mass from first principles. However, due to the limit of computational resources, lattice baryon masses have to be extrapolated to the physical point. Chiral perturbation theory, as an effective field theory of low-energy QCD, provides a model independent method to understand nonperturbative strong interactions and to guide the lattice multiple extrapolations. Therefore, we present the interplay between lattice QCD and chiral perturbation theory to systematically study the baryon masses. In the SU(3) sector, we study the lowest-lying octet baryon masses in covariant baryon chiral perturbation theory with the extended-on-mass-shell scheme up to next-to-next-to-next-to-leading order. In order to consider lattice artifacts from finite lattice box sizes, finite-volume corrections to lattice baryon masses are estimated. By constructing chiral perturbation theory for Wilson fermions, we also obtain the discretization effects of finite lattice spacings. We perform a systematic study of all the latest n_f=2+1 lattice data with chiral extrapolation (m_q → m_q^phys.), finite-volume corrections (V→∞), and continuum extrapolation (a→0). We find that finite-volume corrections are important to describe the present lattice baryon masses. On the other hand, the discretization effects of lattice simulations up to O(a²) are of the order 1% when a≈0.1 fm and can be safely ignored. Furthermore, we find that the lattice data from different collaborations are consistent with each other, though their setups are quite different. Using the chiral formulas of octet baryon masses, we accurately predict the octet baryon sigma terms via the Feynman-Hellmann theorem by analyzing the latest high-statistics lattice QCD data. Three key factors --- lattice scale setting effects, chiral expansion truncations and strong-interaction isospin-breaking effects --- are taken into account for the first time. In particular, the predicted pion- and strangeness-nucleon sigma terms, sigma_πN=55(1)(4) MeV and sigma_sN =27(27)(4) MeV, are consistent with the most latest lattice results of nucleon sigma terms. With the success in the study of octet baryon masses, we also present a systematic analysis of the lowest-lying decuplet baryon masses in covariant baryon chiral perturbation theory by simultaneously fitting n_f=2+1 lattice data. A good description for both the lattice and the experimental decuplet baryon masses is achieved. The convergence of covariant baryon chiral perturbation theory in the SU(3) sector is discussed. Furthermore, the pion- and strangeness-sigma terms for decuplet baryons are predicted by the Feynman-Hellmann theorem. In addition, understanding the excitation spectrum of hadrons is still a challenge, especially the first positive-parity nucleon resonance, the Roper(1440). The baryon spectrum shows a very unusual pattern that the Roper state is lower than the negative-parity state N(1535). Most lattice studies suggest that the Roper mass exhibits much larger chiral-log effects than that of the nucleon. Therefore, we calculate the Roper mass in chiral perturbation theory by explicitly including the nucleon/Delta contributions. The mixed contributions between nucleon and Roper to the baryon masses are taken into account for the first time. A first analysis of lattice Roper masses is presented
