Description
Preliminary results about the prompt production of some heavy quarkonium states are presented, which are based on an event sample of pPb collisions at a center-of-mass energy of 8.16 TeV, collected by CMS detector during 2016 and corresponding to an integrated luminosity of 180 nb$^{-1}$. $\chi_{c1}\rightarrow$ J/$\psi \gamma$ and $\chi_{c1}\rightarrow$ J/$\psi \gamma$ decays are used for these studies. The ratio of the prompt production cross sections for the $\chi_{c1}$ and $\chi_{c2}$ states ($\sigma (\chi_{c2})/\sigma(\chi_{c1})$) has been measured in the bins of the J$/\psi$ transverse momentum and track multiplicity.
