Strong Vertices of Doubly Heavy Spin-3/2 Baryons with Light Pseudoscalar Mesons

Abstract

The strong coupling constants are basic quantities that carry information of the strong interactions among the baryon and meson multiplets as well as information on the natures and internal structures of the involved hadrons. These parameters enter to the transition matrix elements of various decays as main inputs and they play key roles in analyses of the experimental data including various hadrons. We determine the strong coupling constants among the doubly heavy spin-$3/2$ baryons, ${\Xi }_{Q{Q}^{\prime }}^{\ast }$ and ${\Omega }_{Q{Q}^{\prime }}^{\ast }$, and light pseudoscalar mesons, $\pi$, $K$ and $\eta$, using the light-cone QCD. The values obtained for the strong coupling constants under study may be used in construction of the strong potentials among the doubly heavy spin-3/2 baryons and light pseudoscalar mesons.
