Spectrum and decay matrix elements of B and D-mesons in lattice NRQCD
Joachim Hein
Abstract
We discuss recent results on the excitation spectra of B and D-mesons obtained in the framework of non-relativistic lattice QCD in the quenched approximation. The results allow for the determination of the -mass of mb,(mb,)= 4.34(7) GeV in O(αs3) in the perturbative matching. The determination of the decay constants fBs and fDs is discussed in detail. Results for the matrix elements of semi-leptonic B to D decays are shown.
