A comparison of direct photon, π0 in pp and pp interactions at the CERN ISR
We have measured the production of direct photons, π0's, and η's in pp and pp collisions at √s=53 GeV in the range 2≈pT≈6 GeV/c for the central rapidity region |y| 0.4. No statistically significant difference between pp̄ and pp interactions is observed. © 1985.
