Forward-backward asymmetry of Drell-Yan lepton pairs in pp collisions at 8 TeV

The measurement of the forward-backward asymmetry A$_{\rm FB}$ of oppositely charged lepton pairs produced via an intermediate $Z/\gamma^*$ at $\sqrt{s} = 8$~TeV is presented. The data sample corresponds to an integrated luminosity of 19.7~fb$^{-1}$. The A$_{\rm FB}$ measurement is performed for dil...

Sumario:The measurement of the forward-backward asymmetry A$_{\rm FB}$ of oppositely charged lepton pairs produced via an intermediate $Z/\gamma^*$ at $\sqrt{s} = 8$~TeV is presented. The data sample corresponds to an integrated luminosity of 19.7~fb$^{-1}$. The A$_{\rm FB}$ measurement is performed for dilepton masses between 40~GeV and 2~TeV and rapidity up to 5. The final distributions are corrected for detector resolution, acceptance, and final-state radiation effects. The measured A$_{\rm FB}$ distributions are found to be consistent with the standard model predictions.
