Calculation of the nucleon sigma term and strange quark content with two flavors of dynamical overlap fermions
H. Ohki, H. Fukaya, S. Hashimoto +5
We present a calculation of the nucleon sigma term on two-flavor QCD configurations with dynamical overlap fermions. We analyse the lattice data for the nucleon mass using the bary…
Pion vector and scalar form factors with dynamical overlap quarks
JLQCD, TWQCD collaborations, : +11
We calculate the pion vector and scalar form factors in two-flavor QCD. Gauge configurations are generated with dynamical overlap quarks on a 16^3 x 32 lattice at a lattice spacing…
Light meson spectrum with dynamical overlap fermions
J. Noaki, S. Aoki, T. W. Chiu +8
We report on a numerical simulation with 2+1 dynamical flavors of overlap fermions. We calculate pseudo-scalar masses and decay constants on a $16^3\times 48 \times (0.11 {\rm fm})…
Lattice study of vacuum polarization function and determination of strong coupling constant
E. Shintani, S. Aoki, T. W. Chiu +7
We calculate the vacuum polarization functions on the lattice using the overlap fermion formulation.By matching the lattice data at large momentum scales with the perturbative expa…
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…
