Title: Measurement of differential cross sections in the $$\phi^*$$ variable for inclusive Z boson production in pp collisions at $$\sqrt{s}=$$ 8 TeV

Abstract

Measurements of differential cross sections d$$\sigma$$/d$$\phi^*$$ and double-differential cross sections d$$^2\sigma$$/d$$\phi^*\,$$d$|y|$ for inclusive Z boson production are presented using the dielectron and dimuon final states. The kinematic observable $$\phi^*$$ 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/$$\sigma$$)$$\,$$d$$\sigma$$/d$$\phi^*$$, within the fiducial kinematic region, is measured with a precision of better than 0.5% for $$\phi^*$$<1. The measurements are compared to theoretical predictions and they agree, typically, within few percent.
