Abstract
We present a lattice investigation of heavy-light mesons in the quenched approximation, using nonrelativistic QCD for the heavy quark and a clover-improved Wilson formulation for the light quark. A comprehensive calculation of the heavy-light spectrum has been performed for various heavy quark masses around the b. Our results for the Bs−Bd splitting agree well with the experimental value. We find the Λb−B splitting to be compatible with experiment, albeit with large error bars. Our B*−B splitting is slightly low, which could be explained as an effect of quenching. For the first time, we are able to estimate the mass of P states at the B and compare them with experiment.Keywords
