The QCD Running Coupling

, 2020
We review the present knowledge for $\alpha_s$, the fundamental coupling underlying the interactions of quarks and gluons in QCD. The dependence of $\alpha_s(Q^2)$ on momentum transfer $Q$ encodes the underlying dynamics of hadron physics -from color ...

The index of the overlap Dirac operator on a discretized 2d non-commutative torus

, 2007
The index, which is given in terms of the number of zero modes of the Dirac operator with definite chirality, plays a central role in various topological aspects of gauge theories. We investigate its properties in non-commutative geometry.

Status and Future Perspectives for Lattice Gauge Theory Calculations to the Exascale and Beyond

, 2019
In this and a set of companion whitepapers, the USQCD Collaboration lays out a program of science and computing for lattice gauge theory. These whitepapers describe how calculation using lattice QCD (and other gauge theories) can aid the interpretation ...

Summary: Working Group on QCD and Strong Interactions

, 2002
In this summary of the considerations of the QCD working group at Snowmass 2001, the roles of quantum chromodynamics in the Standard Model and in the search for new physics are reviewed, with empahsis on frontier areas in the field.

A non-perturbative computation of the B-meson decay constant and the b-quark mass in HQET

, 2003
A lattice computation of the B-meson decay constant and the mass of the b-quark to leading order in the heavy quark effective theory is presented. The involved renormalization problems are solved non-perturbatively, and the continuum limit is taken.

Heavy-quark free energy at finite temperature with 2+1 flavors of improved Wilson quarks in fixed scale approach

, 2009
The free energy between a static quark and an antiquark is studied by using the color-singlet Polyakov-line correlation at finite temperature. We perform simulations on $32^3 \times 12$, 10, 8, 6, 4 lattices in the high temperature phase with the RG ...
