Light Gluino and Tevatron Data

Abstract

A very light gluino ($m_{\tilde{g}}\text{lsim}2\text{gev}$) is still consistent with experimental data and is attractive from a theoretical standpoint. This has been shown to lead to a small gluino content of the proton. We use this effect to demonstrate that such a light gluino could lead to a striking enhancement, at Tevatron, of monojets accompanied by large missing momentum. A reanalysis of the existing data may thus rule out a light gluino for a common squark mass of upto $\sim 600\text{gev}$.
