ANOMALOUS TRILINEAR GAUGE COUPLINGS AND ANGULAR VARIABLES by KEVIN SIEHL May 2020 Advisor: Dr. Robert Harr Major: Physics Degree: Doctor of Philosophy A study of techniques for improving limits placed on anomalous trilinear couplings of electroweak gauge bosons is presented. Electroweak gauge bosons couple to one another as well as to fermions. Deviations of these couplings from their standard model values would be a sign of new physics. Parameters that affect the couplings of the gauge bosons to each other also affect their helicity, which in turn may be measured from their decay products. Angles between the decay planes of the gauge bosons, as well as between their decay products, are measured. The analysis uses 35.9 fb−1 of proton-proton collision data from the LHC taken with the CMS detector. Building on a prior analysis that measured the fiducial cross section of pp→ WW/WZ → `νjj, we show that angular variables can improve limits on anomalous couplings even further.
