Differential decay rate for semileptonic decays
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
We present our study on semileptonic decay form factors with NRQCD action for heavy quark from a quenched lattice QCD simulation at =5.9 on a lattic…
B^0-\bar{B}^0 mixing with quenched lattice NRQCD
JLQCD Collaboration, N. Yamada, S. Aoki +15
We present our recent results for the B-parameters, which parameterize the ΔB=2 transition amplitudes. Calculations are made in quenched QCD at β=5.7, 5.9, and 6.1, using NRQCD for…
Light hadron spectroscopy with two flavors of O(a) improved dynamical quarks
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
We report on our study of light hadron spectrum and quark masses in QCD with two flavors of dynamical quarks. Simulations are made with the plaquette gauge action and the non-pertu…
Perturbative renormalization of the four-quark operators in lattice NRQCD
S. Hashimoto, K-I. Ishikawa, T. Onogi +3
We present a perturbative calculation of the renormalization constants for the four-quark operators, which is needed to evaluate the bag parameters and in lattic…
Renormalization of the ΔB=2 four-quark operators in lattice NRQCD
S. Hashimoto, K-I. Ishikawa, T. Onogi +3
We calculate perturbative renormalization constants for the ΔB=2 four-quark operators in lattice NRQCD. Continuum operators \bar{b}γ_μ(1-γ_5)q~ \bar{b}γ_μ(1-γ_5)q and \bar{b}(1-γ_5…
Perturbative Renormalization Factors of Baryon Number Violating Operators for Improved Quark and Gauge Actions in Lattice QCD
S. Aoki, Y. Kuramashi, T. Onogi +1
We calculate one-loop renormalization factors of three-quark operators, which appear in the low energy effective Lagrangian of the nucleon decay, for -improved quark action a…
