Description
This talk will focus on RBC/UKQCD's most recent analysis for $B \rightarrow \pi l \nu$ and $B \rightarrow D l \nu$ semileptonic form factors. Heavy quarks have been simulated with the Columbia formulation of the relativistic heavy quark (RHQ) action, and light quarks with a domain-wall fermion action. The decays have been investigated over six ensembles. The form factor dependence on the three RHQ action parameters and its contribution to the error budget will be presented, as well as preliminary results. This work forms part of RBC/UKQCD's larger effort on predicting semileptonic $B_{(s)}$ decay form factors with RHQ b quarks.
