Description
Studies of charm and charmonia production provide important tests of QCD. During 2010 and 2011 the LHCb experiment collected a dataset corresponding to about 1/fb of integrated luminosity in proton-proton collisions at sqrt(s) = 7 TeV. We present measurements of the production of J/psi, psi(2S), chi_c1 and chi_c2 as well as their cross-section ratio, and a cross-section ratio of chi_c to J/psi. We also present measurements of double charm production which is the first observation at hadronic collisions. The results are compared to theoretical predictions.
