Preliminary study of $B_B$ parameter using Lattice NRQCD

Abstract

We present the preliminary result of the calculation of $B_B$ parameter using lattice NRQCD. The calculation is performed on a $16^3\times 48$ quenched lattice at $\beta =5.9$ with clover light quark. The use of lattice NRQCD enables us to investigate the $1/m_Q$ correction from the static limit. The observed mass dependence is well described by the vacuum saturation.
