We analyze the cutoff dependence of the fermion contribution to the finite temperature free energy density in O(g 2) lattice perturbation theory for several improved staggered fermion actions. Cutoff effects are drastically reduced for the Naik action and an action with improved rotational symmetry of the quark propagator. We show that improvement of rotational symmetry at O(g 2) further reduce...

A lattice QCD calculation of the kaon B parameter BK is carried out with the Wilson quark action in the quenched approximation at β = 6/g2 = 5.9− 6.5. The mixing problem of the ∆s = 2 four-quark operators is solved nonperturbatively with full use of chiral Ward identities employing four external quarks with an equal off-shell momentum in the Landau gauge. This method, without invoking any effec...

This talk is a review of our studies of instantons and their properties as seen in our lattice simulations of SU (2) gauge theory. We have measured the topological susceptibility and the size distribution of instantons in the QCD vacuum. We have also investigated the properties of quarks moving in instanton background field configurations, where the sizes and locations of the instantons are tak...

Lattice QCD allows us to simulate QCD at non-zero temperature and/or densities. Such equilibrium thermodynamics calculations are relevant to the physics of relativistic heavy-ion collisions. I give a brief review of the field with emphasis on our work.
