Forward-Backward Charge Asymmetry in Z production at the LHC.
We present here a first study on the determination of the effective weak mixing angle (from the measurement of the Forward-Backward Asymmetry), $\sin^{2}\theta^{lept}_{eff}$ with one statistical precision better than the current results, 10^-4. To reach such a precision it will be necessary to ident...

| description | We present here a first study on the determination of the effective weak mixing angle (from the measurement of the Forward-Backward Asymmetry), $\sin^{2}\theta^{lept}_{eff}$ with one statistical precision better than the current results, 10^-4. To reach such a precision it will be necessary to identify the electrons in the forward regions of the detector. It is demonstrated that one can reach an electron-jet rejection of more than 100 with an efficiency on electron reconstruction better than 50%, by using a multivariate analysis. |
