Determination of the Neutral B Meson and Neutral B(s) Meson Mixing Matrix Elements in 2+1 Lattice QCD
… presents a calculation and results for the matrix elements relevant for the analysis of B0 -- B¯0 mixing using the Asqtad (light-quark) and Fermilab (heavy-quark) actions. The calculation is performed on the 2+1 MILC ensembles at three different lattice spacings, and uses staggered …

The brown muck of b^0 and b^0_s mixing: beyond the standard model
Standard Model contributions to neutral B meson mixing begin at the one loop level where they are further suppressed by a combination of the GIM mechanism and Cabibbo suppression. This combination makes B meson mixing a promising probe of new physics, where as yet undiscovered particles and/or …
