| Abstract: | The production of high transverse momentum η mesons from proton-proton collisions has been studied at the CERN ISR. The decay η→γγ was identified in an array of lead-glass ?erenkov counters. The preliminary results, obtained at a total centre-of-mass energy √s=52.7 GeV, show an η signal, which amounts to approximately one half of the π0 cross-section for centre-of-mass transverse momenta between 3 and 5 GeV/c. The production of high transverse momentum π0's was also measured and compared with previous results. |
