Exploring chiral regime with dynamical overlap fermions

Presenter: Hideo Matsufuru — High Energy Accelerator Research Organization (KEK)

I report the status of the dynamical overlap fermion project by the JLQCD collaboration. So far, the simulations have been performed with two flavors of overlap sea quarks in a wide range of sea quark mass including the p-regime and the є-regime on a 163 32 lattice at a=0.12fm. More recently, runs with 2+1-flavor of sea quarks have also started. The talk mainly discusses the physics results on the Nf=2 lattice after mentioning the lattice formulation and algorithms.
