Abstract

We measured exclusive cross sections for p» p annihilation into channels with one or more KS0 at six incident momenta from 403 to 670 MeV/c. No energy dependence was observed in these cross sections, nor was thre any energy dependence in the fractions of various resonances produced in three- and more-body annihilation channels. Taken together with the data of Petitjean, there seems to be a weak indication of a broad enhancement in the p» p KS0KL0 cross section at an incident momentum of around 500 MeV/c. The angular distribution of KS0 suggests the presence of the D13 and/or D33 partial-wave amplitude in this channel.
