Measurement of Anomalous Trilinear Couplings of Electroweak Gauge Bosons

The standard model of particle physics predicts specific couplings between the electroweak gauge bosons with each other. Any deviation of these couplings from the standard model predictions is a sign of new physics. We use MCFM to simulate the production of WW and WZ boson pairs for a range of coupling values around standard model values. Comparing cross sections in the simulations to data allows us to measure anomalous trilinear gauge couplings, or place limits on them.
