We introduce the contributions to the proceedings of Working Group V. The main topics were: present and future experiments dedicated to charm physics, the interplay between high-precision measurements and better control over theoretical uncertainties, and searches for signals of new physics in the charm sector. The comparison of Lattice QCD calculations with precise measurements of charm semi-l...

Determinations of CKM matrix elements are clouded by uncertainties in nonperturbative QCD parameters that relate measurable quantities to the underlying parton-level processes. A principal goal of the CLEO-c program is to provide precision measurements in the c-quark sector that will stimulate lattice QCD theorists to calculate relevant nonperturbative QCD parameters in this sector and to valid...

In these lectures, we introduce finite temperature QCD on the lattice to nonexperts of the subject. We first formulate lattice QCD both at zero and finite temperatures. Then a section is devoted to the topic of improved lattice actions which are becoming an essential ingredient of precision studies of QCD on the lattice. We then discuss about finite temperature SU(3) gauge theory, i.e. QCD with...

We discuss a general strategy to compute the coefficients of QCD chiral Lagrangian by using the lattice regularization of QCD with Wilson fermions. This procedure requires the introduction of an effective Lagrangian for lattice QCD as an intermediate step in the calculation. The continuum QCD chiral Lagrangian can be then obtained by expanding the lattice effective Lagrangian in increasing powe...

Extraction of correct mass splittings between vector and pseudoscalar mesons remains a challenging problem in lattice QCD. While quenched lattice QCD has been unable to extract correct mass splittings [1], so far this problem persists even with full lattice QCD [2]. One may thus ask whether lattice results for baryon mass splittings exhibit similar suppression compared to experimental numbers. ...

It is believed that QCD undergoes phase transitions as temperature T and the baryon density, controlled by a chemical potential μ, increase. For example, an expected phase structure is found in Fig.1 of ref. 1. To theoretically investigate what really happens at non-zero T and μ in QCD, lattice calculations seem ideal. Indeed, as reviewed in ref. 2, lattice QCD investigations are very successfu...

Lattice Gauge Theory enables an ab initio study of the low-energy properties of Quantum Chromodynamics, the theory of the strong interaction. I begin these lectures by presenting the lattice formulation of QCD, and then outline the benchmark calculation of lattice QCD, the light-hadron spectrum. I then proceed to explore the predictive power of lattice QCD, in particular as it pertains to hadro...
