Strong coupling constants of doubly heavy baryons with vector mesons in QCD

Using the most general form of the interpolating current for baryons, the strong electric and magnetic coupling constants of light vector mesons $\rho $ and ${K}^{\ast }$ with doubly heavy baryons are computed within the light-cone sum rules. We consider 2- and 3-particle distribution amplitudes of the aforementioned vector mesons. The obtained results can be useful in the analysis of experimental data on the properties of doubly heavy baryons conducted at LHC.
