Description

This dissertation describes a measurement of the forward-backward asymmetry(A<sub>FB</sub>) in p$\bar{p}$ → Z/γ* → ee events using 5.0 fb<sup>-1</sup> data collected by the D0 detector at the Fermilab Tevatron. The AFB is measured as a function of the invariant mass of the electron-positron pair. Along with obtaining normalized differential cross section 1/σ x dσ/dM and Z to light quark couplings, we measured the Standard Model(SM) fundamental parameter, the effective weak mixing angle sin<sup>2</sup> θ$lept\atop{eff}$, with an unprecedented precise in light quark sector, namely the single D0 measurement has surpassed the LEP combination of four experiment results of inclusive hadronic charge ... continued below
