  • Abstract Doubly-heavy baryons, with two heavy and one light quarks, are expected to exist in QCD and their masses have been predicted in the quark model. However their existence is not well established so far in experiment. In this work, we explore the possibility of searching for Ξ b c and Ξ c c + in the W -exchange processes, Ξ b c 0 → p K − and Ξ c c + → Σ c + + ( 2520 ) K − . On the basis of perturbative calculations, we estimate the branching ratio of the first decay as BR ( Ξ b c 0 → p… CONTINUE READING
