Hadronic Production of $ch{i}_c$-mesons at LHC

Abstract

Hadronic production of $P$-wave charmonium states ${\chi }_{cJ}$ in hadronic interaction is considered. Using experimental results of CDF and LHCb collaborations we show, that contributions of color-singlet components are dominant. As for color-octet mechanism, we show, that contributions from $P$-wave states can also be observed, while $S$-wave states can be neglected. The best experimental observables that give information about relative importance of color-singlet and color-octet components are the ratios ${\chi }_{c2}/{\chi }_{c1}$ and ${\chi }_{c0}/{\chi }_{c1}$.
