Semileptonic ${\Xi }_c$ baryon decays in the light cone QCD sum rules

Abstract

Form factors of the weak ${\Xi }_c\to \Xi (\Lambda )$ transitions are calculated within the light cone QCD sum rules. The pollutions coming from the contribution of the negative parity ${\Xi }_c^{\ast }$ baryon is eliminated by considering the combinations of sum rules corresponding to the different Lorentz structures. Having obtained the form factors, the branching ratios of the ${\Xi }_c\to \Xi (\Lambda )\ell \nu$ decays are also calculated, and our predictions are compared with the results of other approaches as well as the measurements done by BELLE and ALICE Collaborations.
