Strong vertices of doubly heavy spin-3/2 baryons with light pseudoscalar mesons *

Abstract

The strong coupling constants are basic quantities that carry information on the strong interactions among the baryon and meson multiplets as well as information on the nature and internal structures of the involved hadrons. These parameters are introduced in the transition matrix elements of various decays as main inputs and play key roles in analyses of experimental data including various hadrons. We derive the strong coupling constants among the doubly heavy spin-3/2 baryons, Xi*(QQ') and, Omega*(QQ') and light pseudoscalar mesons, pi, K, and eta, using the light-cone QCD. The values obtained for these constants under study may be used to construct the strong potentials among the doubly heavy spin-3/2 baryons and light pseudoscalar mesons.
