Abstract / Description of output

Our setup for studying heavy-light physics is to use relativistic heavy-quarks (RHQ) and domain-wall light quarks on RBC/UKQCD's 2+1 flavor domain-wall Iwasaki lattices. Here we report on our B-physics project. Tuning the parameters of the RHQ action nonperturbatively for b-quarks we compare results for the bottomonium spectrum with experiment to demonstrate that our method is working using two lattice spacings (a ≈ 0.11 fm and a ≈ 0.08 fm). We also present first numerical data for the B-meson decay constants f B.
