Electroproduction and Photoproduction—Some Gross Characteristics at Extreme Energies

摘要: Certain gross characteristics of inelastic lepton-hadron and photon-hadron collisions at extreme energies are correlated discussed. It is argued that the total electron-proton cross section, for example, increases like ${\mathrm{ln}}^{2}E$ as $E\ensuremath{\rightarrow}\ensuremath{\infty}$, where $E$ incident electron energy, if photoabsorption section tends to a nonzero limit high energies. The behavior partial sections average multiplicities given secondary two kinds processes also In particular, it shown multiplicity any hadron with respect energy same in electroproduction photoproduction processes, could only be logarithmic (or powers thereof). Implications various results context certain existing models
