Resumen/Abstract

Measurements of the five most significant angular coefficients, A0through A4, for Z bosons produced in pp collisions at vs=8TeV and decaying to µ+ µ- are presented as a function of the transverse momentum and rapidity of the Z boson. 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.
