EVIDENCE FOR A PIETA RESONANCE AT 970-MEV PRODUCED IN K-P -] LAMBDAPI+PI-MM AT 3.9-GEV/C, 4.6-GEV/C, AND 5.0-GEV/C

Evidence is presented for the existence of a boson resonance () with M=97015 MeV and <~50 MeV produced in the reaction K-p+(1385)-, - . By studying the - produced in association with +(1385), we are able to rule out possible kinematic effects as a source of the enhancement in our data. We give upper limits to other decay modes such as 2, 3, and KK. © 1969 The American Physical Society.
