Investigation of the semileptonic transition of the $B$ into the orbitally excited charmed tensor meson

Abstract

The transition form factors of the semileptonic $B\to D_2^{\ast }(2460)\ell \bar{\nu }(\ell =\tau ,\mu ,e)$ decay channel are calculated within the framework of the three-point QCD sum rules. The fit functions of the form factors are then used to estimate the total decay width and branching ratio of this transition. The order of branching ratio shows that this channel can be detected at LHCb.
