Some Specific Decay Properties of Multichannel Baryonium

摘要

A new breed of baryonium which is produced due to the coupling between various Banti B channels and reveals some specific decay properties is considered. The system Nanti N-Yanti Y (Y= sigma , delta ) is treated as a physical example and it is shown that there can exist narrow resonances between the thresholds in such system. The peculiar features of these resonances are: the only two-particle decay channel distinguished is Nanti N and among the multimeson decay channels the modes with K-mesons dominate. The ways of the experimental search for such states are briefly discussed. (Atomindex citation 11:547579)
