B and B-c mesons with NRQCD and clover actions

We present preliminary results from our study of the heavy-light spectrum and decay constants. For the heavy quark, we use NRQCD at various masses around and above the b quark mass. For the first time, the heavy quark action and the heavy-light current consistently include corrections at second order in the non-relativistic expansion, as well as the leading finite a corrections. The light quarks are simulated using a tadpole-improved Clover action at various masses in the strange and c quark region.
