A measurement of direct photon production at large p/sub T/ at the CERN ISR

The authors have measured direct photon production in pp collisions at the CERN intersecting storage rings for c.m. energies 31< square root s<63 GeV and transverse momenta up to 9 GeV/c, using segmented lead /liquid-argon calorimeters. The ratio of direct photon to pi /sup 0/ production is si...

description The authors have measured direct photon production in pp collisions at the CERN intersecting storage rings for c.m. energies 31< square root s<63 GeV and transverse momenta up to 9 GeV/c, using segmented lead /liquid-argon calorimeters. The ratio of direct photon to pi /sup 0/ production is significantly larger than zero, starting at p/sub T/ approximately=4 GeV/c and increasing to values of about 0.4 at 9 GeV /c. No significant square root s dependence is seen. (14 refs).
