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


CMS Collaboration; Canelli, F; Chiochia, V; Kilminster, B; Robmann, P; et al (2016). Forward-backward asymmetry of Drell–Yan lepton pairs in pp collisions at $\sqrt{s}$ = 8 TeV. European Physical Journal C - Particles and Fields, 76(6):325.

Abstract

A measurement of the forward-backward asymmetry AFB of oppositely charged lepton pairs (μμ and ee) produced via Z/γ∗ 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 $A_{FB}$ is performed for dilepton masses between 40 GeV and 2 TeV 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.
