Signal at subleading order in lattice HQET

High Energy Physics - Lattice 2009-11-10 v2

Abstract

We discuss the correlators in lattice HQET that are needed to go beyond the static theory. Based on our implementation in the Schr\"odinger functional we focus on their signal-to-noise ratios and check that a reasonable statistical precision can be reached in quantities like fBsf_{B_s} and MBMBM_{B^\star}-M_B.
