Dynamical Wilson quark simulations toward the physical point

Presenter: Yoshinobu Kuramashi — University of Tsukuba

We present preliminary results of the PACS-CS project which simulates 2+1 flavor lattice QCD with the non-perturbatively O(a)-improved Wilson quark action and the Iwasaki gauge action employing the domain-decomposed HMC algorithm to reduce the up-down quark mass toward the physical value. We discuss the physical results and some algorithmic issues. Other recent unquenched results using the Wilson-type quarks are also briefly reviewed.
