A determination of the B0 s and B0 d mixing matrix elements using 2+1 lattice QCD

Fermilab Lattice and MILC Collaborations

Research output: Contribution to journalConference articlepeer-review


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 = fBs √BBs / fBd √BBd = 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.
