Observation of High Energy Quark-Antiquark Elastic Scattering with Mesonic Exchange

Abstract

We studied the high energy quark anti-quark elastic scattering with an exchange of a mesonic state in the $t$ channel with $-t/{\Lambda }_{QCD}^2\gg 1$. Two methods are proposed to eliminate the strong background from bare pomeron, reggized gluon and odderon exchange. The feasibility of measuring mesonic reggeon exchange is discussed.
