Recent progress on HQET lagrangian

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

HQET lagrangian up to 1/m31/m^3 terms is discussed. Consequences of reparameterization invariance are considered. Results for the chromomagnetic interaction coefficient at two loops, and in all orders in the large--β1\beta_1 approximation, are presented.
