Measurement of the weak mixing angle using the forward-backward asymmetry of Drell-Yan events in pp collisions at 8 TeV

A measurement is presented of the effective leptonic weak mixing angle (sin2 θ eff) using the forward– backward asymmetry of Drell–Yan lepton pairs (μμ and ee) produced in proton–proton collisions at √s = 8 TeV at the CMS experiment of the LHC. The data correspond to integrated luminosities of...
