PHOTOPRODUCTION OF K$sup +$ MESONS

The photoproduction in hydrogen K/sup +/ mesons in association with hyperons was studied using an 1160-Mev bremsstrahlung beam from the Connell Synchrotron. The K mesons were selected with a magnetic analyzer and counter telescope system. They were further identified by bringing them to rest in a stopping block and by the detection of the particles arising from their decay. The angular distribution for the associated production of K/sup +/ mesons with LAMBDA /sup 0/ hyperons at th photon energies of 980 and 1010 Mev was studied. Measurements were also made of the cross section as a function of photon energy for the center-of-mass angle of 85 degrees. The results of these measurements are compatible with S-wave production. The photoproduction of SIGMA /sup 0/ hyperons in association with K/suip +/ mesons was measured for one set of kinematical conditions. The measured (K/sup +/- SIGMA /sup 0/) cross section is comparable to that of the (K/sup +/- LAMBDA /sup 0/) process. (auth)
