Jets and Energy Flow in Photon-Proton Collisions at HERA
H1-Collaboration, S. Aid et al
Abstract
Properties of the hadronic final state in photoproduction events with large transverse energy are studied at the electron-proton collider HERA. Distributions of the transverse energy, jets and underlying event energy are compared to pp data and QCD calculations. The comparisons show that the γp events can be consistently described by QCD models including -- in addition to the primary hard scattering process -- interactions between the two beam remnants. The differential jet cross sections dσ/dETjet and dσ/dηjet are measured.
