Description
Semileptonic $B_{(s)}$ decays are of great phenomenological interest and allow to extract the CKM matrix elements or test lepton flavor universality.
We explore $B_{(s)}$ decays with vector final states by studying $B_s\to D_s^*$ using the narrow width approximation. Taking advantage of existing data we present first results for the form factors using our setup based on RBC-UKQCD's 2+1 flavor domain-wall fermion and Iwasaki gauge field action. Light quarks are simulated with domain-wall fermions, whereas bottom quarks are simulated with the relativistic heavy quark (RHQ) action.
