Exclusive decays of the Xi bc(+) with light meson production, Xi(+)(bc) -> Xi R-++(cc) are analyzed. In the framework of the factorization model, the matrix elements of the considered reactions are written as a product of Xi(bc )-> Xi W-cc and W -> R transition amplitudes. As a result, theoretical and experimental investigation of these decays allows us to test the physics of heavy and light quark sectors. Presented are the branching fractions of these reactions, as well as the distributions over the invariant mass of the light system and some other kinematical variables. Our calculations show that the probabilities of the considered reactions are high enough, so presented results could help with observations of the yet unseen Xi(bc )baryon.
