Semileptonic c baryon decays in the light cone QCD sum rules
Abstract
Form factors of the weak c () transitions are calculated within the light cone QCD sum rules. The pollutions coming from the contribution of the negative parity c* 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 c () 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.
