Widths in the conversion of. sigma. and hyperons in nuclear matter

Journal Article · · Sov. Phys. J. (Engl. Transl.); (United States)
OSTI ID:6312014
The widths of the conversion processes ..sigma.. N ..-->.. anti ..lambda.. N, (-) N ..-->.. ..lambda.. ..lambda.. in nuclear matter were calculated based on the model of single-boson exchange. It was established that the conversion width for ..sigma.. is significantly reduced by the interference of the contributions of separate mesons to the conversion amplitude. The conversion width obtained for (-) in nuclear matter turned out to be less than 1 MeV.
