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 ofp _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$Sp\bar pS$.
