摘要：
A study on muon pairs produced through an intermediate Z/gamma*, in pp collisions at the LHC, at a center-of-mass energy of 7TeV, is presented. After a selection aimed at enhancing the contribution from Z boson decay, the topology of the events is analyzed, and the forward-backward asymmetry is measured. The result is then used to test a method to measure the effective weak mixing angle sin(2) theta(eff)(W). This note summarizes the results obtained with 2011 data collected by the ATLAS experiment at the LHC, corresponding to an integrated luminosity of 4.8 fb(-1)
