Measurement of forward-backward asymmetry A{sub FB} and of the weak mixing angle in processes of dilepton production in proton-proton collisions at <##> $ /sqrt s $√s = 7 TeV in the CMS experiment at the LHC
The results obtained by measuring the forward-backward asymmetry (A{sub FB}) of Drell-Yan lepton pairs in proton-proton collisions at <##> $ /sqrt s $√s = 7 TeV at the LHC are presented. This asymmetry is measured as a function of the dilepton mass and rapidity in the dielectron and dimuon channels. The values of A{sub FB} were found for invariant masses of dileptons in the range of 40 ⩽ M{sub ll} ⩽ 600 GeV. The results for the effective weak mixing angle that were deduced from data on dimuon production in Drell-Yan processes are also presented. The respective data sample was collected by using the Compact Muon Solenoid (CMS) detector over the period spanning the years 2010 and 2011. The measured asymmetry and the effective weak mixing are consistent with the respective Standard Model predictions.
