Abstract

The decay constants of the heavy-light pseudoscalar mesons are studied in a high statistics run using the Wilson action at beta = 6.0 and beta = 6.2, and the clover action at beta = 6.0. The systematics of O(a) discretisation errors are discussed. Our best estimates of the decay constants are: f(D) = 218(9) MeV, f(D)/f(D s) = 1.11(1) and we obtain preliminary values for f(B).
