Semileptonic transition of P wave bottomonium ${\chi }_{b0}(1P)$ to $B_c$ meson

Abstract

Taking into account the two-gluon condensate contributions, the transition form factors enrolled to the low energy effective Hamiltonian describing the semileptonic ${\chi }_{b0}\to B_c\ell \bar{\nu },(\ell =(e,\mu ,\tau ))$ decay channel are calculated within three-point QCD sum rules. The fit function of the form factors then are used to estimate the decay width of the decay mode under consideration.
