Description

I will present a very brief overview of a nearly complete study of the vector and tensor decay constants of $B^*$, $B_s^*$, $D^*$, and $D_s^*$ mesons from fully relativistic $n_f = 2+1+1$ lattice QCD. We use multiple lattice spacings, with both heavy and physical light-quark masses. Ours will be not only the first lattice results for the $B^*$ and $B_s^*$ tensor decay constants, but also the first with percent-level precision. These results constitute key ingredients in precision tests of Standard-Model and beyond-Standard-Model heavy-flavour phenomenology.
