J/ψ and ψ(2S) production in pp collisions at $ \sqrt {s} = 7{\text{Tev}} $
A bstract A measurement of the J/ψ and ψ (2S) production cross sections in pp collisions at $ \sqrt {s} = 7{\text{TeV}} $ with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 pb −1 . Using a fit to the …
