Abstract

We present a calculation of the hadronic matrix elements relevant to B⁰ − B^{¯ 0} mixing and a preliminary result for the SU (3) breaking ratio ξ = f_Bs √B_Bs / f_Bd √B_Bd = 1.205(52). The calculation is done on the MILC lattices with 2+1 flavors of Asqtad-improved sea quarks. We use the Asqtad action for the light valence quarks and the Fermilab action for the b quark.
