A lattice NRQCD calculation of the $B^0-{\bar{B}}^0$ mixing parameter B_B

S. Hashimoto, K-I. Ishikawa, H. Matsufuru +2

We present a lattice calculation of the B meson B-parameter B_B using the NRQCD action. The heavy quark mass dependence is explicitly studied over a mass range between m_b and 4m_b…
