Measurement of the cross-section for Z → e[superscript +]e[superscript -] production in pp collisions at √s =7 TeV
A measurement of the cross-section for pp → Z → e[superscript +]e[superscript −] is presented using data at √s = 7 TeV corresponding to an integrated luminosity of 0.94 fb[superscript −1]. The process is measured within the kinematic acceptance pT > 20 GeV/c and 2 < η < 4.5 for the daught...

| description | A measurement of the cross-section for pp → Z → e[superscript +]e[superscript −] is presented using data at √s = 7 TeV corresponding to an integrated luminosity of 0.94 fb[superscript −1]. The process is measured within the kinematic acceptance pT > 20 GeV/c and 2 < η < 4.5 for the daughter electrons and dielectron invariant mass in the range 60–120 GeV/c[superscript 2]. The cross-section is determined to be
σ(pp→Z→e[superscript +]e[superscript −]) = 76.0±0.8±2.0±2.6 pb where the first uncertainty is statistical, the second is systematic and the third is the uncertainty in the luminosity. The measurement is performed as a function of Z rapidity and as a function of an angular variable which is closely related to the Z transverse momentum. The results are compared with previous LHCb measurements and with theoretical predictions from QCD. |
