Abstract

We present the first preliminary results for the semileptonic form factor h_A₁ (w = 1)/ρ_A_j at zero recoil for the B → D∗lv decay using lattice QCD with four flavors of sea quarks. We use the HISQ staggered action for the light valence and sea quarks (the MILC HISQ configurations), and the Oktay-Kronfeld (OK) action for the heavy valence quarks.
