## Measurement of differential cross sections in the kinematic angular variable ? * for inclusive Z boson production in pp collisions at ?s=8 TeV

Abstract: Measurements of differential cross sections d?/d?* and double-differential cross sections d2?/d?*d|y| for inclusive Z boson production are presented using the dielectron and dimuon final states. The kinematic observable ?* correlates with the dilepton transverse momentum but has better resolution, and y is the dilepton rapidity. The analysis is based on data collected with the CMS experiment at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 fb?1. The normalised cross section (1/?) d?/d?*, within the fiducial kinematic region, is measured with a precision of better than 0.5% for ?* < 1. The measurements are compared to theoretical predictions and they agree, typically, within few percent.
