We derive the quark mass dependence of mz, mAwi and fir, using the chiral perturbation theory which includes the a2 effect associated with the explicit choral symmetry breaking of the Wilson-type fermions, in the case of the ZVf = 2 degenerate quarks. By fitting the mass dependence of rnt and mAwI,

We discuss the implementation of a Sheikholeslami-Wohlert term for simulations of lattice QCD with dynamical Wilson fermions as required by Symanzik's improvement program. We show that for the Hybrid Monte Carlo or Kramers equation algorithm standard even-odd preconditioning can be maintained. We de

We report on a numerical reinvestigation of the Aoki phase in full lattice QCD with two flavors of unimproved Wilson fermions. For zero temperature the Aoki phase can be confirmed at inverse coupling p = 4.

We perturbatively determine O(a) boundary improvement coefficients at l-loop for the Schri5dinger Functional coupling with improved gauge actions. These coefficients are required to implement the l-loop O(a) improvement in full QCD simulations for the coupling with the improved gauge actions. To thi
