This paper presents measurements from the ATLAS experiment of the forwardbackward
asymmetry in the reaction pp → Z/γ∗ → l
+l
−, with l being electrons or muons,
and the extraction of the effective weak mixing angle. The results are based on the full
set of data collected in 2011 in pp collisions at the LHC at √
s = 7 TeV, corresponding
to an integrated luminosity of 4.8 fb−1
. The measured asymmetry values are found to
be in agreement with the corresponding Standard Model predictions. The combination
of the muon and electron channels yields a value of the effective weak mixing angle of
sin2
θ
lept
eff = 0.2308±0.0005(stat.)±0.0006(syst.)±0.0009(PDF), where the first uncertainty
corresponds to data statistics, the second to systematic effects and the third to knowledge
of the parton density functions. This result agrees with the current world average from the
Particle Data Group fit
