Measuring the Higgs trilinear coupling is one of the most important physics drivers of the high-luminosity LHC and future colliders given its insight into the mechanism of electroweak symmetry breaking. After a review of proposed collider probes for this interaction, the speaker will demonstrate how a nonstandard value for this coupling predicts unitarity violation at high energies. Depending on the theoretical assumptions, this occurs at energies above 5-13 Tera Electron Volts (TeV) for an order one trilinear modification. This gives a model-independent argument for the energy scale where new physics has to appear by motivating an energy target for future colliders.
The seminar is free and open to the public. No registration is required. Seating is on a first come, first served basis.
