Light hadron spectrum in 2+1 flavor full QCD by CP-PACS and JLQCD Collaborations
T. Ishikawa, S. Aoki, M. Fukugita +13
CP-PACS and JLQCD Collaborations are carrying out a joint project of the 2+1 flavor full QCD with the RG-improved gauge action and the non-perturbatively -improved Wil…
Charmed meson spectra and decay constants with one-loop improved relativistic heavy quark action
Y. Kayaba, S. Aoki, M. Fukugita +8
We calculate charmed meson spectra and decay constants in lattice QCD employing one-loop improved heavy quark action and axial-vector currents. In quenched simulations at $a…
Heavy quark expansion parameters from lattice NRQCD
JLQCD Collaboration, N. Tsutsui, S. Aoki +15
Using the lattice NRQCD action for heavy quark, we calculate the heavy quark expansion parameters and for heavy-light mesons and heavy-light-light baryons. The resu…
Non-trivial phase structure of QCD with -improved Wilson fermion at zero temperature
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
JLQCD collaboration recently started the QCD simulations with the -improved Wilson fermion action employing an exact fermion algorithm developed for odd number of qua…
B meson decay constant from quenched Lattice QCD
JLQCD collaboration, S. Aoki, M. Fukugita +8
A lattice QCD calculation of the B meson decay constant is presented. In order to investigate the scaling violation associated with the heavy quark, parallel simulations are carrie…
