Reexamination of the role of the Delta* resonances in the pp -> nK(+)Sigma(+) reaction
Source PublicationPHYSICAL REVIEW C
Language英语
AbstractIn this work, the role of the Delta* resonances in the process of pp -> nK(+)Sigma(+) are systematically investigated with the effective Lagrangian approach and the isobar model. We find that a P-31 state, either Lambda*(1750) or Lambda*(1910) is favored by the data while the P-33 state, namely Delta*(1920), has small contribution. Besides, either the subthreshold S-31 Delta*(1620) resonance or strong n Sigma final state interaction or both have a possible contribution at near threshold region, depending on the measured cross sections. We demonstrate the invariant mass distributions and the Dalitz plots in order to investigate whether it is possible to distinguish the controversial K Sigma production mechanism in these observables.
