$B\to \pi \ell \nu$ and $B\to \pi {\ell }^{+}{\ell }^{-}$ semileptonic form factors from unquenched lattice QCD

Daping Du, Jon A. Bailey, A. Bazavov +11

We update the lattice calculation of the $B\to \pi$ semileptonic form factors, which have important applications to the CKM matrix element $|V_{ub}|$ and the $B\to \pi {\ell }^{+}{\ell }^{-}$ rare…
