| Abstract: The double-differential cross sections of the promptly-produced J/$\psi$ and $\psi$(2S) mesons, in transverse momentum, $p_{\rm T}$, and absolute rapidity, $|y|$, are measured in pp collisions at $\sqrt{s} = 7$\,TeV, using a dimuon sample collectedby CMS in 2011, corresponding to an integrated luminosity of 4.9\,fb$^{-1}$. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay length, and cover a broad $p_{\rm T}$ range, extending from 15 to 120\,GeV in the J/$\psi$ case and to 100\,GeV in the $\psi$(2S) case, when integrated in the $|y|<1.2$ window. | ||
