Measurements of the production of jets of particles in association with a Z boson in pp collisions at $\sqrt{s}$ = 7 TeV are presented, using data corresponding to an integrated luminosity of 4.6/fb collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum $p_T > 30$ GeV and rapidity $|y| < 4.4$. This Rivet module implements the event selection for Z decaying into electrons and uses the data measured explicitly in this channel (not the combined results shown in the paper plots). If you want to use muonic events, please refer to ATLAS\_2013\_I1230812\_MU.

Measurements of the production of jets of particles in association with a $Z$ boson in $pp$ collisions at $\sqrt{s}$ = 7 TeV are presented, using data corresponding to an integrated luminosity of 4.6/fb collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in $Z$ events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum $p_T > 30$ GeV and rapidity $|y| < 4.4$. This Rivet module implements the event selection for the weighted combination of both decay channels and uses the data from that combination (as in the paper plots). But for simplification of its usage it only requires events with the electronic final state (muonic final state will be ignored). This allows to use it with either pure electronic samples, or mixed electron/muon events. If you want to use it with a pure muon sample, please refer to ATLAS\_2013\_I1230812\_MU.

A measurement of angular correlations in Drell-Yan lepton pairs via the phi-star observable is presented.This variable probes the same physics as the Z/gamma* boson transverse momentum with a better experimental resolution. The Z/gamma* -> ee and Z/gamma*->mu mu decays produced in proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = \unit{7}{\text{TeV}}$ are used. Normalised differential cross sections as a function of phi-star are measured separately for electron and muon decay channels. The cross section is also measured double differentially as a function of phi-star for three independent bins of the Z boson rapidity.

The Z pT at $\sqrt{s} = 7$\;TeV is measured using electron and muon $Z$ decay channels. The dressed leptons definition uses photons clustered in a cone around the charged leptons, while the bare lepton definition uses the post-FSR charged leptons only in the $Z$ reconstruction. The data used in the bare leptons calculation are based on a forward application of a PHOTOS-based energy loss correction and are hence not quite model-independent.

Production of jets in association with a $Z/\gamma^*$ boson in proton--proton collisions at $\sqrt{s} = 7$ TeV with the ATLAS detector. The analysis includes the full 2010 data set, collected with a low rate of multiple proton--proton collisions in the accelerator, corresponding to an integrated luminosity of 36 pb$^{-1}$. Inclusive jet cross sections in $Z/\gamma^*$ events, with $Z/\gamma^*$ decaying into electron or muon pairs, are measured for jets with transverse momentum $p_T > 30$ GeV and jet rapidity $|y| < 4.4$.
