On Production of Heavy Charged Particles in γγ Fusion at Planned pp Colliders

Abstract

Production of heavy fermions in ultraperipheral collisions ($$pp \to p + \gamma \gamma + p \to p + {{\chi }^{ + }}{{\chi }^{ - }} + p$$) and the semi-exclusive reaction ($$pp \to p + \gamma \gamma {\text{*}} + X \to p + {{\chi }^{ + }}{{\chi }^{ - }} + X$$) is considered. Differential and total cross sections for the energies of the planned pp colliders are presented.
