Increases of Inelastic Total Cross Section and of Average Multiplicity in Inelastic P+P ->P+X Reaction

Photon-photon Total Inelastic Cross-section *

We discuss predictions for the total inelastic γγ cross-section and their model dependence on the input parameters. We compare results from a simple extension of the Regge Pomeron exchange model as well as predictions from the eikonalized mini-jet model with recent LEP data. It is by now established that all total cross-sections, including photopro-duction, rise as the c.m. energy of the collid...

Averaging of the inelastic cross-section measured

Positron interactions with water-total elastic, total inelastic, and elastic differential cross section measurements.

Utilising a high-resolution, trap-based positron beam, we have measured both elastic and inelastic scattering of positrons from water vapour. The measurements comprise differential elastic, total elastic, and total inelastic (not including positronium formation) absolute cross sections. The energy range investigated is from 1 eV to 60 eV. Comparison with theory is made with both R-Matrix and di...

On total inelastic cross sections and the average depth of the maximum of extensive air showers

The model dependence of the development of extensive air showers generated by high-energy cosmic-ray particles in the atmosphere is studied. The increase of proton–proton and proton–air inelastic cross sections and values for the elasticity are varied in the hadronic interaction model QGSJET. Using the CORSIKA simulation program, the impact of these changes is investigated on air shower observa...

Diffractive production and the total cross section in deep inelastic scattering∗

We explore the consequences for diffractive production, γp → Xp, in deep inelastic scattering at low values of x ∼= Q/W 2 ≪ 1 that follow from our recent representation of the total photoabsorption cross section, σγ∗p, in the generalized vector dominance/color dipole picture (GVD/CDP) that is based on the generic structure of the two-gluon exchange from QCD. Sum rules are derived that relate th...
