Probing Broken Symmetries: The Higgs Boson and Beyond

At the Large Hadron Collider, events containing a W boson and at

least one more heavy boson (W or Z) have played important roles

in probing the fundamental symmetries of particle physics. Early on,

they provided constraints on the allowed mass range of the Higgs

boson and existence of any additional Higgs-like states. These

events also provide measurements of electroweak boson

self-interactions and the world’s best limits on deviation of such

interactions from the expected behavior at high energies. Going

forward, they are important for probing the nature of the

newly-discovered Higgs boson and other new phenomena that can

manifest themselves at high energies. I will summarize the results

from analyzing the data from the CMS experiment.
