B0−B¯ 0 mixing and decay constants from lattice QCD

UKQCD Collaboration

Research output: Contribution to journalConference articlepeer-review


We present updates of our results for neutral B-meson mixing and leptonic decay constants obtained in the quenched approximation from a mean-field-improved Sheikholeslami-Wohlert action at two values of lattice spacing. We consider quantities such as BBd(s), fD(s), fB(s) and the full ∆B = 2 matrix-elements, as well as the corresponding SU(3)-breaking ratios.
