Abstract
This document presents the determination of the J/ψ and ψ(2S) differential cross sections in pp collisions at 7 TeV, as a function of transverse momentum and in several rapidity ranges, on the basis of the 2010 data collected by CMS, corresponding to an integrated luminosity of 37 pb−1. The b → J/ψ and b → ψ(2S) fractions are also determined, enabling to separate the prompt and non-prompt contributions and compare to theory calculations. We also report the measurement of the γ(1S), γ(2S), and γ(3S) differential cross sections as a function of transverse momentum and rapidity.
