Search for the S=+1 pentaquarks in quenched lattice QCD
Toru T. Takahashi, Takashi Umeda, Tetsuya Onogi +1
We study spin hadronic states in quenched lattice QCD to search for a possible pentaquark resonance. Our work is the first systematic lattice QCD study which prope…
Parameter dependence of the topology change and the scaling properties of the topology conserving gauge action
H. Fukaya, T. Onogi, S. Hashimoto +2
The topology conserving gauge action proposed by Luescher is expected to reduce the number of non-smooth gauge configurations as well as the topology change compared to the convent…
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…
Lattice Determination of Semileptonic Form Factors
Tetsuya Onogi
We report on the Lattice determination of the semileptonic form factors by lattice QCD. Comparison with the light-cone QCD sum rules are made for $\Btopi, \Btorho$ semileptonic dec…
Exploration of sea quark effects in two-flavor QCD with the O(a)-improved Wilson quark action
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
We explore sea quark effects in the light hadron mass spectrum in a simulation of two-flavor QCD using the nonperturbatively O(a)-improved Wilson fermion action. In order to identi…
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…
