Preliminary study of BB parameter using Lattice NRQCD
Abstract
We present the preliminary result of the calculation of BB parameter using lattice NRQCD. The calculation is performed on a 163 × 48 quenched lattice at β=5.9 with clover light quark. The use of lattice NRQCD enables us to investigate the 1/mQ correction from the static limit. The observed mass dependence is well described by the vacuum saturation.
