Abstract

The production of direct photons has been measured relative to π⁰'s in the rapidity range 2.00 < y < 2.75 in pp collisions at s = 63 GeV at the CERN Intersecting Storage Rings. The γ/π⁰ ratio increases from {less-than or approximate}2% at p_T = 1.5 GeV/c to ∼8% at p_T = 4.25 GeV/c, similar to the value observed near 90°. The results indicate no strong enhancement of single-photon production due to quark bremsstrahlung in this kinematic region.
