$B\to D^{\ast }\ell {\nu }_{\ell }$ semileptonic form factors from lattice QCD with Möbius domain-wall quarks

Y. Aoki, B. Colquhoun, H. Fukaya +5

We calculate the form factors for the $B\to D^{\ast }\ell {\nu }_{\ell }$ decay in 2+1 flavor lattice QCD. For all quark flavors, we employ the Möbius domain-wall action, which preserves chiral…
