Semileptonic transition of P wave bottomonium $χ_{b0}(1P)$ 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 $χ_{b0}\rightarrow B_{c}\ell\barν, (\ell=(e,μ,τ))$ 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.
