  In this paper, we analyze the doubly heavy spin-3/2--spin-1/2 baryons and
light meson vertices within the method of light-cone QCD sum rules. These
vertices are parametrized in terms of one (three) coupling constant(s) for the
pseudoscalar (vector) mesons. The said coupling constants are calculated for
all possible transitions. The results presented here can serve to be useful
information in experimental as well as theoretical studies of the properties of
doubly heavy baryons.
