AbstractAbstract
[en] Semileptonic decays of Bc meson are considered in the framework of the constituent model of the meson and of the QCD sum rules. It is shown that the discrepancy in the width predictions, obtained in different approaches, may be cancelled if the corrections caused by the Coulomb-like gluonic interactions of the quarks are taken into account within the sum rules
