Abstract

Identification of charmonium states at hadron colliders has mostly been limited to leptonic decays of the J/{\psi}. In this paper we present and algorithm to identify hadronic decays of charmonium states (J/{\psi}, {\psi}(2S), \chi_{c0,1,2}) which make up the large majority of all decays. The algorithm is able to identify hadronic J/ψJ/\psi decays with an efficiency of 36\% while suppressing a background of quark and gluon jets by a factor 100.
