Untangling the heavy-flavor mess: status of the Fermilab-MILC calculation of the $B_{(s)}\to D_{(s)}^{(\ast )}\ell \nu$ form factors

Alejandro Vaquero, Carleton DeTar, Aida El-Khadra +6

We present the status of calculations of the form factors of the most relevant heavy-to-heavy and heavy-to-light decay channels. Using seven $N_f=2+1+1$ HISQ ensembles, with latt…
