Photon and its hadronic interaction

Hadronic photon-photon scattering at LEP

Hadronic interactions of two quasi-real photons have been studied extensively both during the LEP1 and the LEP2 data taking periods. The higher energies available at LEP2 in particular opened regions of phase space where hadronic processes can be predicted reliably by perturbative QCD calculations, usually available to next-to-leading order in the strong coupling constant for the process concer...

Hadronic photon-photon interactions at high energies.

Photon-photon collisions are investigated in the framework of the two-component Dual Parton Model. The model contains contributions from direct, resolved soft and resolved hard interactions. All free parameters of the model are determined in fits to hadronhadron and photon-hadron cross section data. The model is shown to agree well to hadron production data from hadron-hadron and photon-hadron ...

Total Hadronic Cross-Section of Photon-Photon Interactions at LEP

The total hadronic cross-section σγγ(W ) for the interaction of real photons, γγ → hadrons, is measured for γγ centre-of-mass energies 10 ≤ W ≤ 110 GeV. The cross-section is extracted from a measurement of the process ee → eeγγ → ee + hadrons, using a luminosity function for the photon flux together with form factors for extrapolating to real photons (Q = 0 GeV). The data were taken with the OP...
