Update of $textbarV_b̧textbar$ from the $barBto Dtextasciicircum*ellbarnu$ form factor at zero recoil with three-flavor lattice QCD

We compute the zero-recoil form factor for the semileptonic decay $barBtextasciicircum0to Dtextasciicircum*+elltextasciicircum-barnu$ (and modes related by isospin and charge conjugation) using lattice QCD with three flavors of sea quarks. We use an …
