Photoproduction 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.

متن کاملINELASTIC ELECTRON SCATTERING AND THE MULTI - REGGE MODEL t
We investigate the multi-Regge model in the kinematic region where the four momentum of one initial particle is large and spacelike. These kinematics occur in inelastic electron scattering through single virtual photon exchange. We predict a rapid fall off in the cross section as the virtual particle becomes more spacelike, contradicting present data. (Submitted to Phys . Rev. ) t Supported by ...
متن کاملRegge Theory and Multi–Reggeon Exchange
We analyze conformal field theory 4–point functions of the form A ∼ 〈O1 (x1)O2 (x2)O1 (x3)O2 (x4)〉, where the operators Oi are scalar primaries. We show that, in the Lorentzian regime, the limit x1 → x3 is dominated by the exchange of conformal partial waves of highest spin. When partial waves of arbitrary spin contribute to A, the behavior of the Lorentzian amplitude for x1 → x3 must be analyz...
متن کاملRegge pole model for all vector meson exclusive photoproduction by real and virtual photons
A model based on a dipole Pomeron framework for vector meson exclusive photoproduction by real and virtual photons shows very good agreement with the experimental data. The model does not violate unitarity constrains and describes in a universal manner all the available data for ρ, ω, ϕ, J/ψ and Υ vector meson photoproduction in the region of energies 1.7 ≤ W ≤ 250 GeV and photon virtualities 0...
متن کاملThe Connection between Regge Behavior and Fixed Angle Scattering
The physical origins and dynamical details of Regge behavior are studied by examining a general class of theories which are capable of describing the observed large momentum transfer data and extending them into the intermediate t-range. The mechanism responsible for the smooth connection between the deep scattering region and the Regge region is discussed in detail. We derive a convenient new ...
