Strong BQQ'*BQQ'V vertices and the radiative decays of BQQ* BQQγ in the light-cone sum rules
Abstract
The strong coupling constants of spin-3/2 to spin-1/2 doubly heavy baryon transitions with light vector mesons are estimated within the light-cone QCD sum rules method. Moreover, using the vector-meson dominance ans\"atz, the widths of radiative decays BQQ* BQQ γ are calculated. The results for the said decay widths are compared to the predictions of other approaches.
