Description
Zoom room for seminars: https://cern.zoom.us/j/98750947196?pwd=N1RTS3EzazBha0tURVJOcEZKREFxZz09
Meeting ID: 987 5094 7196
Passcode: 613113
Abstract:
Protons accelerated by the LHC generate a large flux of quasi-real high-energy photons that can interact to produce particles. The ATLAS collaboration recently announced a set of landmark results using the LHC as a photon collider, among which is the first observation of the production of W-boson pairs from the interaction of photons. The process proceeds via trilinear and quartic gauge-boson self interactions involving two W bosons and either one or two photons. It is extremely rare but predicted precisely by electroweak theory of the Standard Model of particle physics, and can serve as a test of its inner structure. Experimentally, it has a remarkably clean signature which, however, is difficult to identify due to the harsh experimental conditions at the LHC.
