Forward–backward asymmetry of Drell–Yan lepton pairs in pp collisions at $$\sqrt{s}$$ = 8 TeV
Abstract
A measurement of the forward–backward asymmetry A FB of oppositely charged lepton pairs (μμ and ee) produced via Z/γ * boson exchange in pp collisions at √s = 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.7 fb-1 collected with the CMS detector at the LHC. The measurement of A FB is performed for dilepton masses between 40 GeV and 2TeV and for dilepton rapidity up to 5. The A FB measurements as a function of dilepton mass and rapidity are compared with the standard model predictions.
