Abstract

We report on the distributions of charge particles produced in association with high-p_T prompt photons and neutral pions in pp collisions at s = 63 GeV and σ = 90° in the centre of mass. We find photons to be relatively unaccompanied by other particles at small angles with respect to the photon, and extract a measurement of the fraction of prompt photons due to bremsstrahlung production. The relative density of positive and negative particles in the system recoiling from the photon has been measured and compared with QCD motivated calculations.
