Abstract:
First we introduce our framework to compute heavy-light physics on the lattice using domain-wall light quarks and relativistic heavy quarks on the 2+1 flavor domain-wall Iwasaki gauge field configurations generated by the RBC and UKQCD collaborations. The distinct feature is our procedure for tuning nonperturbatively the parameters of the relativistic heavy quark action and we demonstrate the quality of our setup by computing bottomonium masses and mass splittings. Finally, we show first results for B-meson decay constants and give an outlook on our current/future projects.
