Semi-leptonic three-body proton decay modes from light-cone sum rules

Semi-leptonic three-body proton decay modes from light-cone sum rules

Abstract Using light-cone sum rule techniques, we estimate the form factors which parametrise the hadronic matrix elements that are relevant for semi-leptonic three-body proton decays. The obtained form factors allow us to determine the differential rate for the decay of a proton (p) into a positron...
