Journal ArticleDOI

Effective lagrangians for bound state problems in QED, QCD, and other field theories

TL;DR: A renormalization group strategy for the study of bound states in field theory is developed in this paper, which is completely different from conventional analyses, based upon the Bethe-Salpeter equation, and it is far simpler
Journal ArticleDOI

Viability of lattice perturbation theory.

TL;DR: It is shown that the apparent failure of QCD lattice perturbation theory to account for Monte Carlo measurements of perturbative quantities results from choosing the bare lattice coupling constant as the expansion parameter, and a new prescription for designing lattice operators that are more continuumlike than conventional operators is suggested.
Journal ArticleDOI

Improved nonrelativistic QCD for heavy-quark physics.

TL;DR: An improved version of nonrelativistic QCD is constructed for use in lattice simulations of heavy-quark physics, and power-counting rules to assess the importance of the various operators in the action and compute all leading-order corrections required by relativity and finite lattice spacing are developed.
Journal ArticleDOI

Highly improved staggered quarks on the lattice with applications to charm physics

TL;DR: In this paper, a new staggered-quark action (HISQ) was proposed, which reduced one-loop taste exchange errors, no tree-level order error, and no tree level order error to leading order in the quark's velocity.
Journal ArticleDOI

High-Precision c and b Masses, and QCD Coupling from Current-Current Correlators in Lattice and Continuum QCD

TL;DR: In this paper, a lattice-QCD analysis of heavy-quark correlators was extended to smaller lattice spacings and larger masses to obtain new values for the c mass and QCD coupling, and for the first time, for the b mass: m{sub c}(3 GeV,n{sub f}=4)=0.986(6) GeV.
