Abstract: (Springer)

Measurements of differential cross sections dσ/dϕ

^{*}

and double-differential cross sections d

^{2}

σ/dϕ

^{*}

d|y| for inclusive Z boson production are presented using the dielectron and dimuon final states. The kinematic observable ϕ

^{*}

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/σ) dσ/dϕ

^{*}

, within the fiducial kinematic region, is measured with a precision of better than 0.5% for ϕ

^{*}

< 1. The measurements are compared to theoretical predictions and they agree, typically, within few percent.
