Abstract

The photoproduction of prompt photons, together with an accompanying jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb(-1). A study of the effective transverse momentum. (k(T)), of partons in the proton, as modelled within the framework of the PYTHIA Monte Carlo. gives a value of (k(T)) = 1.69 +/- 0.18(-0.20)(+0.18) GeV for the gammap centre-of-mass energy range 134 < W < 251 GeV. This result is in agreement with the previously observed trend in hadron-hadron scattering for (k(T)) to rise with interaction energy. (C) 2001 Elsevier Science B.V. All rights reserved.
