Measurement of the production cross section ratio of the charmonium states $\chi_{c2}$ and $\chi_{c1}$ in proton-proton collisions at 7 TeV with CMS
This article presents the observation of the $\chi_c$ resonances and the techniques for the measurement of the $\sigma(pp\rightarrow\chi_{c2}+X)/\sigma(pp\rightarrow\chi_{c1}+X)$ ratio with the CMS detector at LHC. The measurement was performed with $ 4.0$ fb$^{-1} $ of $pp$ collisions at $\sqrt{s}...
