The $D_s$, $D^{+}$, $B_s$ and $B$ decay constants from $2+1$ flavor lattice QCD

A. Bazavov, C. Bernard, C. Bouchard +23

We present a study of the $D$ and $B$ leptonic decay constants on the MILC $N_f=2+1$ asqtad gauge ensembles using asqtad-improved staggered light quarks and clover heavy quarks in…
