Abstract: (APS)
The conversion process Σ+n→Λp has been observed using the sequence K−d→π−(Σ+n)→π−(Λp). The results of this study are that (1) the conversion process at very low energy is dominated by the (ΣN) triplet state; and (2) the reaction is strongly enhanced for Λp masses below Σ+n threshold, suggesting the existence of a bound state in the Σ+n system and, hence, an elastic resonance in the Λp system.
