Abstract

A study of 54930 events of type pp to pi + pi + pi - pi - pi 0 shows evidence for two nearly mass degenerate enhancements in the omega pi mass plots at a mass near to 1200 MeV/c2. This result is in agreement with that reported from annihilations at rest by Frenkiel et al. (see Nucl. Phys., vol.B47, p.61 of 1972).
