On production of heavy charged particles in $\gamma \gamma$ 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 semiexclusive reaction ($pp\to p+\gamma {\gamma }^{\ast }+X\to p+{\chi }^{+}{\chi }^{-}+X$) is considered. Differential and total cross sections for the energies of the planned $pp$ colliders are presented.
