The integrated luminosity of the dataset collected with the CMS detector at the LHC corresponds to 19.7 fb 1 . These measurements provide comprehensive information about the Z boson production mechanisms, and are compared to the QCD predictions at leading order, next-to-leading order, and next-to-next-to-leading order in perturbation theory.
