Description
We present an update for our ongoing calculation of $B$-meson semileptonic form factors, using the highly improved staggered quark (HISQ) action on FNAL-MILC $N_f=2+1+1$ HISQ gauge ensembles. We compute the scalar, vector, and tensor form factors for the $B \to \pi$, $B \to K$, $B_s \to K$, and $B_{(s)} \to D_{(s)}$ transitions . We have recently added data with $a \approx 0.03$ fm into our analysis, allowing simulation directly at the physical $b$-quark mass.
