Study of the [Formula omitted] decay in light cone sum rules

The form factors of the [Formula omitted] decay are calculated in the framework of the light cone QCD sum rules. In the calculations the contribution of the negative parity [Formula omitted] baryon is eliminated by constructing the sum rules for different Lorentz structures. Furthermore the branchin...

Zusammenfassung:The form factors of the [Formula omitted] decay are calculated in the framework of the light cone QCD sum rules. In the calculations the contribution of the negative parity [Formula omitted] baryon is eliminated by constructing the sum rules for different Lorentz structures. Furthermore the branching ratio of the semileptonic [Formula omitted] decay is calculated. The numerical study for the branching ratio of the [Formula omitted] decay indicates that it is quite large and could be measurable at future planned experiments to be conducted at LHCb.
