First Nonperturbative Test of a Relativistic Heavy Quark Action in Quenched Lattice QCD
Y. Kayaba, S. Aoki, M. Fukugita +6
We perform a numerical test of a relativistic heavy quark(RHQ) action, recently proposed by Tsukuba group, in quenched lattice QCD at fm. With the use of the improvem…
Neutron electric dipole moment with external electric field method in lattice QCD
E. Shintani, S. Aoki, N. Ishizuka +6
We discuss a possibility that the Neutron Electric Dipole Moment (NEDM) can be calculated in lattice QCD simulations in the presence of the CP violating term. In this paper we…
An application of the UV-filtering preconditioner to the Polynomial Hybrid Monte Carlo algorithm
CS Collaboration, K-I. Ishikawa, S. Aoki +8
We apply the UV-filtering preconditioner, previously used to improve the Multi-Boson algorithm, to the Polynomial Hybrid Monte Carlo (UV-PHMC) algorithm. The performance test for t…
2+1 Flavor Lattice QCD with Luescher's Domain-Decomposed HMC Algorithm
CS Collaboration, Y. Kuramashi, S. Aoki +9
We report on a study of 2+1 flavor lattice QCD with the -improved Wilson quarks on a lattice at the lattice spacing GeV employing Luescher's dom…
An estimate of the eta and eta-prime meson masses in Nf=2+1 lattice QCD
CP-PACS, JLQCD Collaborations, : +13
Masses of the eta and eta-prime mesons are estimated in Nf=2+1 lattice QCD with the non-perturbatively O(a) improved Wilson quark action and the Iwasaki RG-improved gluon action, u…
2+1 flavor light hadron spectrum and quark masses with the O(a) improved Wilson-clover quark formalism
JLQCD Collaboration, T. Ishikawa, S. Aoki +14
We present a summary of results of the joint CP-PACS and JLQCD project toward a 2+1 flavor full QCD simulation with the O(a)-improved Wilson quark formalism and the Iwasaki gauge a…
