Hadronic photon-photon interactions at high energies.

چکیده
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 collisions. The multiparticle production in hadron-hadron, photon-hadron and photon-photon collisions as predicted by the model is compared. Strong differences are only found as function of the transverse momentum variable. The hadron production in photon-photon collisions at present and future electron-positron colliders is studied using photon spectra according to the equivalent photon approximation, according to beamstrahlung and according to backscattered laser radiation.

Jets and jet multiplicities in high-energy photon-nucleon interactions.
We discuss the theory of jet events in high-energy photon-proton interactions using a model which gives a good description of the data available on total inelastic γp cross sections up to √ s=210 GeV. We show how to calculate the jet cross sections and jet multiplicities and give predictions for these quantities for energies appropriate for experiments at the HERA ep collider and for very high ...
متن کاملPHOTON STRUCTURE a
The photon is one of the fundamental gauge bosons of the Standard Model without self-couplings and without intrinsic structure. It couples to any kind of charged particle, which allows it to fluctuate directly into fermion-antifermion pairs and into bound states, vector mesons, which have the same spin-parity (J = 1−−) as the photon. Photon-photon interactions therefore become possible through ...

متن کاملCalculating Weighting Factors for Mixing Megavoltage Photon Beams to Achieve Desirable Dose Distribution in Radiotherapy
Background: In radiotherapy, low-energy photon beams are better adapted to the treated volume, and the use of high-energy beams can reduce hot spots in the radiation therapy. Therefore, mixing low and high energies with different ratios can control the rate of hotspots, as well as the dose distribution of the target volume.Material and Methods: The percentage depth doses (PDDs) were calculated ...
متن کاملImproving the equivalent-photon approximation in electron–positron collisions
The validity of the equivalent-photon approximation for two-photon processes in electron–positron collisions is critically examined. Commonly used forms to describe hadronic two-photon production are shown to lead to sizeable errors. An improved two-photon luminosity function is presented, which includes beyond-leading-logarithmic effects and scalar-photon contributions. Comparisons of various ...
