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 $\chi_{c0}/\chi_{c1}$ .
