Measurement of the Forward-Backward Charge Asymmetry($$A_{FB}$$) using $$p\bar{p}\rightarrow Z/\gamma*\rightarrow e^+e^-$$ events in $$\sqrt{S} = 1.96$$ TeV
- Univ. of Science and Technology of China, Hefei (China)
This dissertation describes a measurement of the forward-backward asymmetry(AFB) in p$$\bar{p}$$ → Z/γ* → ee events using 5.0 fb-1 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 sin2 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 asymmetry.
