Forward-Backward Asymmetry and the Weak Mixing Angle with e+e- Pairs in ATLAS

by Christoph Weinsheimer (Uni Mainz)

Thursday, February 13, 2014 from to (Europe/Berlin)
at DESY Hamburg ( 3a )
Description
The electroweak unification includes the rotation of fundamental gauge boson states to the observed Z and \gamma bosons introducing the
Weak Mixing Angle \sin^2 \theta_W as a free parameter of the standard
model. An observable asymmetry arising from the parity violating
nature of the weak force yields experimental access to this parameter.

This talk describes a measurement of the forward-backward asymmetry
and the succeeding extraction of the weak mixing angle in pp-Collisions
at the ATLAS experiment using e^{+}e^{-} final states. The underlying
dataset has been recorded in 2012 at \sqrt{s}= 8 TeV comprising
a total integrated luminosity of 20.3 fb^{-1}.
