Observation of the charmonium states $\rm \chi_{c1}$ and $\rm \chi_{c2}$ through the radiative decay $\rm J/\psi + \gamma$
This performance plot shows the results for the observation of the charmonium states $\rm \chi_{c1}$ and $\rm \chi_{c2}$ through the radiative decay $\rm J/\psi + \gamma$ produced in pp collisions at $\sqrt{s}$~=~7~TeV using 40 $\rm pb^{-1}$ data collected at the CMS detector. Photons are reconstr...
