AbstractAbstract
[en] In the first part of this work the inclusive cross section for J/ψ production in inelastic √(s) = 7 TeV pp collisions has been determined within vertical stroke y vertical stroke < 0.9 and in the decay channel J/ψ → e+e-. The result for the integrated value is: σJ/ψ(vertical stroke y vertical stroke < 0.9) = 10.7 ± 0.8 (stat.) ± 1.4 (syst.) ± 0.4 (lumi.) μb. Together with the ALICE measurement in the μ+μ- decay channel at forward rapidities and data from other experiments this result fills the gap at mid-rapidity for a comprehensive measurement of the J/ψ rapidity distribution. Furthermore, results of the differential analysis as a function of the J/ψ transverse momentum were presented. Finally the data are shown together with various theoretical predictions representing the current status of the three most common theoretical approaches for the description of quarkonia production: the Color-Singlet Model, the Color-Evaporation Model and NRQCD.
