 Longitudinal Z-Boson Polarization and the Higgs Boson Production Cross Section at the Large Hadron Collider / Amoroso, S. (DESY) ; Fiaschi, J. (Liverpool U., Dept. Math. ; Munster U., ITP) ; Giuli, F. (CERN ; Rome U., Tor Vergata ; INFN, Rome) ; Glazov, A. (DESY) ; Hautmann, F. (Antwerp U. ; Oxford U., Theor. Phys.) ; Zenaiev, O. (CERN) Lepton pairs are produced copiously in high-energy hadron collisions via electroweak gauge boson exchange, and are one of the most precisely measured final states in proton-proton collisions at the Large Hadron Collider (LHC).
