Experimental Results on the Decay Sequences PSI'(3685) Implies gamma P/sub C//chi Implies gamma gamma J/PSI, gamma pi exp + pi exp - , gamma K exp + K exp - and the Decays PSI' Implies etaJ/PSI, pi exp 0 J/PSI.

摘要

In an analysis of the gamma gamma mu exp + mu exp - final state observed in PSI' decays we investigate the radiative cascade transitions PSI' implies gamma P/sub c//chi implies gamma gamma J/PSI and the decays PSI' implies etaJ/PSI, pi exp 0 J/PSI. Furthermore, the decay sequences PSI' implies gamma chi implies gamma pi exp + pi exp - , gamma K exp + K exp - are observed in a study of hadron pairs from PSI' decays. Decay branching ratios (or limits on them) are presented and compared to those from other experiments. (Atomindex citation 10:486126)
