Inelastic diffraction data and the effective Pomeron trajectory
A further analysis of inelastic diffraction data at the ISR and SPS-Collider confirms the relatively flat s–independent Pomeron trajectory in the high–|t| domain, 1 < |t| < 2 GeV2, reported earlier by the UA8 Collaboration. At |t| = 1.5 GeV2, α = 0.92± 0.03 is in agreement with the trajectories found in diffractive photoproduction of vector mesons at HERA. This suggests a universal fixed Pomero...
متن کاملInelastic diffraction data and the Pomeron trajectory
We demonstrate that all available inclusive pp and p̄p single diffraction data from ISR to Tevatron require an effective Pomeron trajectory whose intercept, α(0), changes with energy; it decreases from 1.10 at low energy to about 1.03 at the SPS and perhaps smaller at the Tevatron. This result, when combined with a relatively s–independent trajectory, α(t) ∼ 0.92 − 0.95 in the range, 1.0 < |t| <...
متن کاملInelastic diffraction and meson radii
It is shown that meson radii can be extracted from diffractive scattering experiments of the type: m + p → m + X, where p stands for the target proton, and m for the incident charged meson π, π, K, or K. The basis of the method used to perform this extraction is the QCD-based SOC-picture for inelastic diffraction in high-energy hadron-hadron and lepton-hadron collisions proposed in a recent Let...
متن کاملDeep Inelastic Scattering, Diffraction
These lectures include an introduction to the partonic description of the proton, the photon and the ‘colour singlet’, as seen in inclusive and semi-inclusive DIS, in e+e− collisions, and in diffractive processes, respectively. Their formal treatment using structure, fragmentation, and fracture functions is outlined giving an insight into the perturbative QCD framework for these functions. Exam...
متن کاملDiffraction in Deep Inelastic Scattering
Different theoretical methods used for the description of diffractive processes in small-x deep inelastic scattering are reviewed. The semiclassical approach, where a partonic fluctuation of the incoming virtual photon scatters off a superposition of target colour fields, is used to explain the basic physical effects. In this approach, diffraction occurs if the emerging partonic state is in a c...
