Precision study of B^* Bπcoupling for the static heavy-light meson
S. Negishi, H. Matsufuru, T. Onogi
We compute the B^*Bπcoupling \hat{g}_{\infty} for static heavy-light meson using all-to-all propagators. It is shown that low-mode averaging with 100 low-lying eigenmodes indeed im…
Heavy flavor physics from lattice QCD
Tetsuya Onogi
I review the recent status of heavy flavor physics results from lattice QCD. In particular, I focus on the heavy-light decay constants, the bag parameters, the form factors, and th…
Mobility edge and locality of the overlap-Dirac operator with and without dynamical overlap fermions
JLQCD Collaboration, N. Yamada, S. Aoki +8
We perform a systematic study of low-lying eigenmodes of with various gauge actions to find the optimal choice for dynamical overlap fermion simulations, with which one may a…
JLQCD's dynamical overlap project
JLQCD Collaboration, T. Kaneko, S. Aoki +11
We present an overview of our project of large-scale simulations with dynamical overlap fermions. The first production run in two-flavor QCD is on-going using the Iwasaki gauge act…
Improvement of algorithms for dynamical overlap fermions
JLQCD Collaboration, Hideo Matsufuru, Hidenori Fukaya +7
We investigate the algorithms for dynamical overlap fermions aiming at improving the performance for large-scale simulations. We look for the best combination of Hybrid Monte Carlo…
Dynamical overlap fermions in the epsilon-regime
JLQCD collaboration, H. Fukaya, S. Hashimoto +7
We report on the two-flavor QCD simulation in the epsilon-regime using the overlap fermion formulation. Sea quark mass is reduced to ~ 2 MeV on a 16^3x32 lattice with the lattice s…
Dynamical overlap fermion at fixed topology
JLQCD collaboration, S. Hashimoto, S. Aoki +7
We launched a project to perform dymanical fermion simulations using the overlap fermion formulation for sea quarks. In order to avoid the appearace of near-zero modes of the hermi…
Lattice gauge action suppressing near-zero modes of H_W
JLQCD collaboration, H. Fukaya, S. Hashimoto +5
We propose a lattice action including unphysical Wilson fermions with a negative mass m_0 of the order of the inverse lattice spacing. With this action, the exact zero mode of the…
