Production of new particles with photons and energy below 12 GeV
Description
An attempt was made to measure the cross section for the production of the psi(3105) in order to compare the photoproduction cross section for the psi with those of the other vector mesons. It was found that the measured angular and energy spectra for the psi can be fitted by assuming an elastic production cross section for photon energies between 9.0 and 11.8 GeV. Also a search was made for other bosons (or leptons) of mass greater than 1.5 GeV that decay into two showering particles in order to establish the existence of a postulated spin-O state of mass 3.0 GeV which can decay into two photons. No evidence was found for any new particle. Preliminary upper limits on the cross section times branching ratio are presented for some of the data
