Jets and Energy Flow in Photon-Proton Collisions at HERA
Abstract
Description
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 $\overline{p}p$ 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 $dσ/dE_T^{jet}$ and $dσ/dη^{jet}$ are measured.
