Semileptonic Xi(c) baryon decays in the light cone QCD sum rules

2021    Aliev, T. M.; Bilmis, S.; Savci, M.

Form factors of the weak Xi(c) -> Xi( )(A) transitions are calculated within the light cone QCD sum rules. The pollution coming from the contribution of the negative parity Xi(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 Xi(c -> )Xi(c )(Lambda)lv decays are also calculated, and our predictions are compared with the results of other approaches as well as the measurements done by the BELLE and ALICE collaborations.
