$B\to D^{(\ast )}\ell \nu$ semileptonic decays in lattice QCD with domain-wall heavy quarks

T. Kaneko, Y. Aoki, B. Colquhoun +5

We calculate the $B\to D^{(\ast )}\ell \nu$ form factors in 2+1 flavor relativistic lattice QCD by employing the Möbius domain-wall action for all quark flavors. Our simulations are ca…
