Findings

Updated lattice QCD results for B-meson decay constants

Discussion of future prospects for reducing theoretical uncertainties

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 -> \mu^+ \mu^-) and Br(B_d -> \mu^+ \mu^-) using those results.
