Multihadron decays of new mesons
Description
We discuss the hadronic decays of the new I = 0 mesons seen in e+e-, PSI-3,105 or PSI-3,695 with G = - and CHI or X with G = +. We present some isospin inequalities for I = 0 pure pionic final states, and a discussion of anti-K K and ETA-549, ETA-958 fractions. We also present a statistical model analysis of pion final states, and conclude that a large fraction of hadronic PSI-3,105 decays contain something besides pions and anti-K K probably ETA-549 and ETA-958, possibly radiative modes.

Wir diskutieren den Zerfall der neuen I = 0 Mesonen in e+e-, PSI-3.105 oder PSI-3.695 mit G = - und CHI oder X mit G = +. Wir geben einige Isopin-Ungleichheiten fuer I = 0 reine Pion-Endzustaende an und diskutieren die Fraktionen anti-K K und ETA-549, ETA-958. Daneben wird eine statistische Modellanalyse von Pion-Endzustaenden vorgelegt, die zu der Annahme fuehrt, dass ein grosser Teil der hadronischen PSI-3.105-Zerfaelle nicht nur Pionen und anti-K K enthaelt, sondern wahrscheinlich auch ETA-549 und ETA-958 und moeglicherweise Strahlungs-Modes enthaelt.
