Precision measurement of forward Z boson production in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV
A precision measurement of the Z boson production cross-section at s√ = 13 TeV in the forward region is presented, using pp collision data collected by the LHCb detector, corresponding to an integrated luminosity of 5.1 fb−1. The production cross-section is measured using Z → μ+μ− events within the...

| description | A precision measurement of the Z boson production cross-section at s√ = 13 TeV in the forward region is presented, using pp collision data collected by the LHCb detector, corresponding to an integrated luminosity of 5.1 fb−1. The production cross-section is measured using Z → μ+μ− events within the fiducial region defined as pseudorapidity 2.0 < η < 4.5 and transverse momentum pT > 20 GeV/c for both muons and dimuon invariant mass 60 < Mμμ < 120 GeV/c2. The integrated cross-section is determined to be σ(Z→μ+μ−)=196.4±0.2±1.6±3.9 pb, where the first uncertainty is statistical, the second is systematic, and the third is due to the luminosity determination. The measured results are in agreement with theoretical predictions within uncertainties. |
