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…
Meson correlators in the epsilon-regime of two-flavor lattice QCD
JLQCD collaboration, H. Fukaya, S. Aoki +7
We calculate the meson correlators in the -regime of two-flavor QCD. On a lattice with fm, the lattice simulations are performed with the dynamical…
High precision study of B*B pi coupling in unquenched QCD
Hiroshi Ohki, Hideo Matsufuru, Tetsuya Onogi
The B* B pi coupling is a fundamental parameter of chiral effective Lagrangian with heavy-light mesons and can constrain the B->pi l nu form factor in the soft pion limit which wil…
Theta vacuum physics from QCD at fixed topology
Sinya Aoki, Hidenori Fukaya, Shoji Hashimoto +1
We propose a method to obtain physical quantities in the theta vacuum from those at fixed topology, which are different by finite size effects. Extending the work by Brower et al.,…
