Identification of charmonium states at hadron colliders has mostly
been limited to leptonic decays of the J/\psiJ/ψ.
In this paper we present an algorithm to identify hadronic decays of
charmonium states (J/\psiJ/ψ,
\psiψ(2S),
\chi_{c0,c1,c2}χc0,c1,c2)
which make up the large majority of all decays. The algorithm is able to
identify hadronic J/\psiJ/ψ
decays with an efficiency of 36% while suppressing a background of quark
and gluon jets by a factor 100.
