Glueball plus pion production in hadron collisions

Abstract

Using a non--relativistic gluon bound--state model for glueballs (G), we compute the subprocess $q\bar{q}\to G\pi$, and we therefrom derive the yield of the overall reaction $p\bar{p}\to G\pi X$, assuming the glueball and the pion to be emitted with their transverse momenta large, opposite and approximately equal. Numerical results are presented in the form of $p_T$ spectra for various glueball candidates and their possible quantum states, assuming those particles to be produced, in the type of reactions here considered, at high--energy $p\bar{p}$ colliders such as the CERN Spp̄S.
