Exclusive Decays of the Doubly Heavy Baryon ${\Xi }_{bc}$

Abstract

Exclusive decays of the ${\Xi }_{bc}^{+}$ with light mesons production, ${\Xi }_{bc}^{+}\to {\Xi }_{cc}^{++}\mathcal{R}$ are analyzed. In the framework of the factorization model the matrix elements of the considered reactions are written as a product of ${\Xi }_{bc}\to {\Xi }_{cc}W$ and $W\to \mathcal{R}$ transition amplitudes. As a result theoretical and experimental investigation of these decays allow us to test the physics of heavy and light quarks' 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 observation of yet unseen ${\Xi }_{bc}$ baryon.
