Regge cuts and charge-exchange reactions in the triple-Regge region

Abstract

We estimate th\ifmmode \dot{e}\else \.{e}\fi{} Regge-cut contribution to the inclusive reactions ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}X$, ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}\ensuremath{\eta}X$, and ${K}^{\ensuremath{-}}p\ensuremath{\rightarrow}{\overline{K}}^{0}X$ in the triple-Regge region. We find that the magnitude of the cut is less than about one-half that of triple-Reggepole contribution near $t=\ensuremath{-}0.5$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. We discuss the implications of this for the interpretation of the $t$ dependence of these reactions.
