Double diffractive meson production and the BFKL Pomeron at $e^{+}{e}^{-}$ colliders

Abstract

In this Letter we study the double diffractive vector meson production in $e^{+}{e}^{-}$ collisions assuming the dominance of the BFKL pomeron exchange. We consider the non-forward solution of the BFKL equation at high energy and large momentum transfer and estimate the total cross section for the process $e^{+}{e}^{-}\to e^{+}{e}^{-}{V}_1{V}_2$ with antitagged $e^{+}$ and $e^{-}$, where $V_1$ and $V_2$ can be any two vector mesons ($V_i=\rho ,\omega ,\varphi ,J/\Psi ,{\rm Y}$). The event rates for the future linear colliders are given.
