Truth Studies Towards a Spin-Correlation Measurement in WW-Boson Production

The precise measurement of the W Boson Pair Production provides an important test of the non-Abelian Structure of the Standard Model (SM) electroweak theory. Deviations of the production cross section or of kinematic distributions from their SM predictions could arise from anomalous triple gauge boson interactions or from new particles decaying into vector bosons and other possible exotic contributions. W Boson Pair Production is also an important source of background to the Higgs boson production [2]. In this report, Monte Carlo (MC) generator studies for a spin correlation measurement of the WW production are presented. Distortions of the (l; l) distribution due to the applied selection criteria are studied. Furthermore, the extrapolation of the measured cross sections to a common fiducial region and the associated systematic uncertainties are investigated.
