Abstract
We present an update for results on B-meson semileptonic decays using the highly improved staggered quark (HISQ) action for both valence and 2+1+1 sea quarks. The use of the highly improved
action, combined with the MILC collaboration’s gauge ensembles with lattice spacings down to $\sim$0.03
fm, allows the $b$ quark to be treated with the same discretization as the lighter quarks. The talk will
focus on updated results for $B_{(s)} \to D_{(s)}$, $B_{(s)} \to K$ scalar and vector form factors.
