Direct production of single photons at the CERN Intersecting Storage Rings

Single-photon production in pp collisions at 30 < rs < 62 GeV has been measured with liquid-argon/lead calorimeters at the CERN ISR. This process, indicative of direct constituent interaction, remains approximately constant with increasing rs. For fixed rs, the single-photon to n° ratio increa...

description Single-photon production in pp collisions at 30 < rs < 62 GeV has been measured with liquid-argon/lead calorimeters at the CERN ISR. This process, indicative of direct constituent interaction, remains approximately constant with increasing rs. For fixed rs, the single-photon to n° ratio increases strongly with increase in PT; y/Tr 0 is 0.25 ± 0.08 at 5.0 < Pr< 6.5 GeV/c for these interactions.
