Abstract

We report on a study of B mesons on N-f = 2 full QCD configurations using an RG-improved gauge action, NRQCD heavy quark action and tadpole-improved clover light quark action. Results on the heavy-light spectrum and the decay constants from 16(3) x 32 lattices at a(-1) approximate to 1.5 GeV are presented, and compared with quenched results obtained with the same action combination at matching lattice spacings.
