  Taking into account the two-gluon condensate contributions, the transition
form factors enrolled to the low energy effective Hamiltonian describing the
semileptonic $\chi_{b0}\rightarrow B_{c}\ell\bar{\nu}, (\ell=(e,\mu,\tau))$
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.
