Contribution
It offers novel experimental data on jet production and subjet multiplicities, enhancing understanding of QCD and photon structure at HERA.
Findings
Jet cross sections agree with QCD predictions
Photon parton densities are constrained by measurements
Differences between quark and gluon jets are observed
Abstract
Measurements of inclusive jet, dijet and three-jet cross sections in photon-proton interactions are presented. These measurements provide new tests of QCD, constrain the parton densities of the photon, and allow searches for new physics. Measurements of the mean subjet multiplicity are reported and used to test the differences between quark and gluon jets.
