We report the results of an experiment made at the CERN ISR to investigate the possible diret production of single photons in pp collisions at √s = 53.2 GeV at 90° and in the pt interval 2.3 to 5.7 GeV/c. The value of the ratio R = nγ/nπ0 is compatible with zero for low pt ⪅ 3 GeV/c but, in spite of the large error, shows a trend to increase for larger pt.

Abstract
We report the results of an experiment made at the CERN ISR to investigate the possible diret production of single photons in pp collisions at √s = 53.2 GeV at 90° and in the pt interval 2.3 to 5.7 GeV/c. The value of the ratio R = nγ/nπ0 is compatible with zero for low pt ⪅ 3 GeV/c but, in spite of the large error, shows a trend to increase for larger pt.File in questo prodotto:
