Abstract

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 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.
