Nucleon sigma term and strange quark content from lattice QCD with exact chiral symmetry
H. Ohki, H. Fukaya, S. Hashimoto +7
We calculate the nucleon sigma term in two-flavor lattice QCD utilizing the Feynman-Hellman theorem. Both sea and valence quarks are described by the overlap fermion formulation, w…
S-parameter and pseudo-Nambu-Goldstone boson mass from lattice QCD
E. Shintani, S. Aoki, H. Fukaya +6
We present a lattice calculation of , one of the low energy constants in Chiral Perturbation Theory, and the charged-neutral pion squared mass splitting, using dynamical ov…
Full QCD calculation of neutron electric dipole moment with the external electric field method
E. Shintani, S. Aoki, Y. Kuramashi
We have calculated the neutron electric dipole moment (NEDM) in the presence of the CP violating term in lattice QCD with 2-flavor dynamical clover quarks, using the external e…
Light meson spectrum with dynamical overlap fermions
J. Noaki, S. Aoki, H. Fukaya +6
We present numerical simulation of QCD with two dynamical quark flavors described by the overlap fermion action on a lattice. We calculate p…
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…
Calculation of Neutron EDM in quenched and full QCD
E. Shintani, S. Aoki, N. Ishizuka +5
We report on a direct lattice calculation of the neutron EDM(NEDM) using the external electric field method in both quenched and full QCD. In quenched QCD, we use a …
