Neutral Pion Photoproduction in a Regge Model
The reaction γp → πp is investigated in the energy range above the resonance region. The amplitudes include the leading Regge singularities in the cross-channel and correctly describe the differential cross section for beam energies above 4 GeV and for momentum transferred above −3 GeV. The energy dependence of the beam asymmetry and the reaction γn → πn seem is quantitative consistent with the...
متن کاملPhotoproduction in the Regge Pole Model
In this paper the Regge pole model is applied to K*(890) photoproduction. Conspiracy relations, kinematic constraints, factorization, and the question of when to set m y = 0 are discussed. Predictions are obtained, in the limit of large s and small t, for ?a , the density matrix, and the K* decay angular distribution. (To be submitted to Physical Review) * Work supported by U. S.

T’ We compare inclusive photoproduction dat$ in the energy range :, ,*.z 3 E Y = 9.0 18.0 GeV to the multi-Regge.. model. ,,The model jncorporates vector-dominance coupling of the photon, the ChewPignotti algorithm for charge as signrnent, and correct treatment of n-bodyphase space. A technique of ordering the particles according to longitudinal momentum is used to enhance features of the data ...
متن کاملRegge-model predictions for K+Σ photoproduction from the nucleon
We present Regge-model predictions for the p(γ,K+)Σ0 and n(γ,K+)Σ− differential cross sections and photon-beam asymmetries in the resonance region. The reaction amplitude encompasses the exchange of K+(494) and K∗+(892) Regge-trajectories, introducing a mere three free parameters. These are fitted to the available p(γ,K+)Σ0 data beyond the resonance region. The n(γ,K+)Σ− amplitude is obtained f...
متن کاملKaon Photoproduction in the Feynman and Regge Theories
A significant progress has been achieved in the experimental side of the strangeness photoproduction. A wealth of new high-statistics data on elementary kaon photoproduction has recently become available in all three isospin channels. Along with some new advancements in the theoretical side this has made the field of kaon electromagnetic production to be of considerable interest. Nevertheless, ...
