$\chi_{c1}$ and $\chi_{c2}$ polarization as a probe of color octet channel
We analyze joint LHC data on the production of $\chi _{c1}$ and $\chi _{c2}$ mesons together with the polarization data obtained very recently by the CMS Collaboration at $\sqrt{s} = 8$ TeV. Our consideration is based on the $k_T$-factorization approach and nonrelativistic QCD formalism for the form...
