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…
Two-flavor QCD simulation with exact chiral symmetry
JLQCD Collaboration, S. Aoki, H. Fukaya +11
We perform numerical simulations of lattice QCD with two flavors of dynamical overlap quarks, which have exact chiral symmetry on the lattice. While this fermion discretization is…
Determination of B*B pi coupling in unquenched QCD
Hiroshi Ohki, Hideo Matsufuru, Tetsuya Onogi
The coupling is a fundamental parameter of chiral effective Lagrangian with heavy-light mesons and can constrain the chiral behavior of , and the fo…
