Abstract

We present an update on the calculation of B^¯ →D^∗`ν¯ semileptonic form factor at zero recoil using the Oktay-Kronfeld bottom and charm quarks on N_f = 2+1+1 flavor HISQ ensembles generated by the MILC collaboration. Preliminary results are given for two ensembles with a ≈ 0.12 and 0.09 fm and M_π ≈310 MeV. Calculations have been done with a number of valence quark masses, and the dependence of the form factor on them is investigated on the a ≈ 0.12 fm ensemble. The excited state is controlled by using multistate fits to the three-point correlators measured at 4–6 source-sink separations.
