Significant progress has been made since 1996 in the determination of the light quark masses from both lattice QCD (LQCD) and QCD sumrules (SR). The evolution in time of the ranges quoted by the Particle Data Group and our best estimates as of DPF2000 are given below. Since the scale dependence between 2 and 1 GeV is very large, we quote all results in the MS scheme at scale μ = 2 GeV. Results ...
We report on some attempts to use lattice QCD to investigate topics in strong interaction phenomenology which are usually interpreted in terms of soft Pomeron exchange.
The confinement mechanism in the nonperturbative QCD is studied in terms of topological excitation as QCDmonopoles and instantons. In the ’t Hooft abelian gauge, QCD is reduced into an abelian gauge theory with monopoles, and the QCD vacuum can be regarded as the dual superconductor with monopole condensation, which leads to the dual Higgs mechanism. The monopole-current theory extracted from Q...
I review the current status of lattice calculations of heavy quark quantities. Particular emphasis is placed on leptonic and semileptonic decay matrix elements.
We report on our results about hadronic tt̄ production at NLO QCD including t, t̄ spin effects, especially on tt̄ spin correlations.
