Calculation of the total cross section for the ionization of H, He, Ne and Ar atoms by bare ions at the high energy range
In the present work, the total cross-section for the ionization of H, He, Ne and Ar atoms by +He2+ ، H+ ، Li3 ions has been calculated. In these calculations, a binary encounter approximation in the form of a two-body process between projectile ions and atomic electrons at the high energy range has been implemented. In order to enter the nuclear role of the target atom, the atomic electron vel...
متن کاملHigh Energy Photoproduction
The study of photoproduction reactions has gained a unique opportunity with the HERA data. The high center of mass energy allows to carry out quantitative tests of QCD, to explore the substructure of both the photon and the proton and to shed new light on soft and diffractive processes. In this report we review the HERA results, comparing them with the reach of fixed target photoproduction expe...
متن کاملProton–Nucleus Cross Section at High Energies
Cross sections for proton inelastic collision with different nuclei are described within the Glauber and multiple scattering approximations. A significant difference between approximate “Glauber” formula and exact calculations with a geometrical scaling assumption for very high-energy cross section is shown. Experimental values of proton–proton cross sections obtained using extensive air shower...

High energy hadronic total cross-section data are found to agree with the predictions of a QCD-string picture.
متن کاملOn charmonia and charmed mesons photoproduction at high energy
In this report we compare the predictions of the collinear parton model and the kT -factorization approach in J/Ψ and D ⋆ meson photoproduction at HERA energies. It is shown that obtained D⋆ meson spectra over pT and η are very similar in the parton model and kT -factorization approach and they underestimate the experimental data. Opposite, the predictions of the both approaches for pT and z-sp...
