Title: Forward–backward asymmetry of Drell–Yan lepton pairs in pp collisions at $$\sqrt{s}$$ = 8 TeV

A measurement of the forward-backward asymmetry $$A_{\mathrm{FB}}$$ of oppositely charged lepton pairs ($$\mu\mu$$ and $$\mathrm{ ee } $$) produced via $$\mathrm{ Z }/\gamma^*$$ boson exchange in pp collisions at $$\sqrt{s} =$$ 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 $$A_{\mathrm{FB}}$$ is performed for dilepton masses between 40 GeV and 2 TeV and for dilepton rapidity up to 5. As a result, the $$A_{\mathrm{FB}}$$ measurements as a function of dilepton mass and rapidity are compared with the standard model predictions.
