Production cross sections of γ-rays, electrons, and positrons in p-p collisions
Abstract
Because the production cross sections of γ rays, electrons, and positrons (e±) made in p-p collisions, σ and σ, respectively, are kinematically equivalent with respect to the parent pion-production cross section σ, we obtain σ directly from the machine data on σ. In Paper I (Sato et al., 2012 [1]), we give explicitly σ, reproducing quite well the accelerator data with LHC, namely σ is applicable enough over the wide energy range from GeV to 20 PeV for projectile proton energy. We discuss in detail the relation between the cross sections, and present explicitly σ that are valid into the PeV electron energy.
