Abstract

The charge asymmetry in the decay η′(958)→π+πγ has been measured using η′ mesons produced in the reaction πp→η′n at 2.1 GeV/c incident pion momentum. A value for the asymmetry of (−6.9±7.8%) was obtained, based on 295±31 events after background subtraction. This result is consistent with C invariance in this decay.
