B-meson decay constants and mixing on the lattice

Abstract

We review the status and future prospects of calculations of B-meson decay constants and non-perturbative inputs relevant for the study of neutral B-meson mixing using lattice QCD techniques. We also discuss the Standard Model prediction for Br(B_s -> μ^+ μ^-) and Br(B_d -> μ^+ μ^-) using those results.
