J/psi prompt and non-prompt cross sections in pp collisions at sqrt(s) = 7 TeV
Measurements of the J/$\psi$ prompt and non-prompt cross sections in proton-proton collisions at 7 TeV by the CMS experiment are presented. The differential cross sections are measured as a function of the J/$\psi$ transverse momentum, up to 30 GeV/c, and in several rapidity ranges. The fraction of...

description | Measurements of the J/$\psi$ prompt and non-prompt cross sections in proton-proton collisions at 7 TeV by the CMS experiment are presented. The differential cross sections are measured as a function of the J/$\psi$ transverse momentum, up to 30 GeV/c, and in several rapidity ranges. The fraction of J/$\psi$ cross section due to b-hadron decays is determined from a fit to the decay length distribution, using the distance between the di-muon vertex and the interaction point. We will also show comparisons between the measurements and several model calculations, for both the prompt and the non-prompt J/$\psi$ cross sections. |
