Abstract

We report on the advances in our unquenched calculation of the matrix elements relevant for the analysis of B0 − B¯0 mixing using the Asqtad (light quark) and Fermilab (heavy quark) actions. We have calculated the hadronic parameters for the mass and width differences in the neutral B meson system. Preliminary results are presented for fB 2 q Bq as well as for the ratio ξ2 = fB 2 s BBs/fB 2 dBBd
