Abstract

We report the results of a search at the Brookhaven National Laboratorys Alternating-Gradient Synchrotron for the (2.2) observed by the Mark III group at the SLAC e+e- storage ring SPEAR. 37 000 p»p K+K- events and 200 000 p»p+- events were studied in the incident-momentum interval from 1.25 to 1.56 GeV/c, corresponding to a mass interval of 110 MeV/c2 about the reported mass. The mass resolution was 3 MeV/c2. We find no evidence for formation and determine that the product B(p»p)B(K+K-) is 2×10-4 for JPC=2++ and 35 MeV/c2.
