Semileptonic Ξc baryon decays in the light cone QCD sum rules

Form factors of the weak Ξc → Ξ(Λ) transitions are calculated within the light cone QCD sum rules. The pollutions coming from the contribution of the negative parity Ξc 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 Ξc → Ξ(Λ)lν 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. ∗ taliev@metu.edu.tr † sbilmis@metu.edu.tr ‡ savci@metu.edu.tr
