摘要：
We present here a study on the determination of the effective weak mixing angle, sin(2) theta(lept)(eff) from the measurement of the forward-backward asymmetry with a high a statistical precision, 10(-4). To reach such a precision it is necessary to identify the electrons in the forward regions of the ATLAS 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.
