Title: Measurement of sin2 θeff and Z-light quark couplings using the forward-backward charge asymmetry in pp -> Z/gamma* -> e+e- events with L=5.0 fb-1 at √s=1.96 TeV

Abstract

We measure the mass dependence of the forward-backward charge asymmetry in 157,553 pp = Z/γ* = e+e- interactions, corresponding to 5.0 fb-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider at √s = 1.96 TeV. The effective weak mixing angle (θeff) from this process involving predominantly the first generation of quarks is extracted as sin2 θeff = 0.2309 ± 0.0008 (stat.) ± 0.0006 (syst.). We also present the most precise direct measurement of the vector and axial-vector couplings of u and d quarks to the Z boson.
