CP-violating TGCs -- Paul Dervan
Plot 1: W production angle at 161GeV. The results from two event generators (ERATO and Stirling) are shown with the results from two analytical (Yellow and Lynn) calculations, with Standard Model couplings.
Notice that there is all big difference between the event generators and the analytical calculations. This is because the calculations do not have the W width included. This is important at threshold.
Plot 2: W production angle at 183GeV. The results from two event generators (ERATO and Stirling) are shown with the results from two analytical (Yellow and Lynn) calculations, with Standard Model couplings. Notice the effects of the W width are negligable at this energy and all predictions agree quite well.
Plot 3: W production angle at 183GeV. The results from two event generators (ERATO and Stirling) are shown with the results from one analytical (Yellow) calculation, with CP-violating couplings. All predictions agree quite well.
Plot 4: Lepton Polar Angle distribution at 183GeV. The results from two event generators (ERATO and Stirling) are shown, with Standard Model couplings. All predictions agree quite well. But not as good as the W production angle distributions
Plot 5: Lepton Polar Angle distribution at 183GeV. The results from two event generators (ERATO and Stirling) are shown, with CP-violating couplings. This distributions do not agree. This is why we get the lepton Polar angle asymmetry with Stirling but not with ERATO. The authors have been notified.
