$B\to D^{(\ast )}\ell \nu$ form factors from lattice QCD with relativistic heavy quarks

T. Kaneko, Y. Aoki, G. Bailas +4

We report on our calculation of the B \to D^(*) \ell νform factors in 2+1 flavor lattice QCD. The Möbius domain-wall action is employed for light, strange, charm and bottom quarks.…
