Reduction of the electroweak correlation in the PDF updating by using the forward-backward asymmetry of Drell-Yan process

Siqi Yang, Yao Fu, Minghui Liu +6

We propose a new observable for the measurement of the forward-backward asymmetry $(A_{FB})$ in Drell-Yan lepton production. At hadron colliders, the $A_{FB}$ distribution is sensi…
