A measurement of the cross-section ratio $\sigma(\chi_{c2})/\sigma(\chi_{c1})$ for prompt $\chi_{c}$ production at $\sqrt{s}$ = 7 TeV in LHCb
The production of the prompt charmonium $\chi_{c}$ states has been studied in proton-proton collisions at the Large Hadron Collider (LHC) at a centre-of-mass energy of $\sqrt{s}$ = 7 TeV. The $\chi_{c}$ mesons are identified through their decays $\chi_{c}\rightarrow J/\psi\gamma$ with $J/\psi \right...
