S@INT Seminar: "Was There an Electroweak Phase Transition?"

Michael Ramsey-Musolf - T.D. Lee Institute/Shanghai Jiao Tong University; University of Massachusetts Amherst
Thursday, March 3, 2022 - 10:00am
PAT C-421 (participants are welcome to join via Zoom as well)

The possible existence of beyond Standard Model physics at the TeV scale or below has important implications for the thermal history of electroweak symmetry-breaking. A first order phase transition -- not possible in the minimal Standard Model with a 125 GeV Higgs boson -- would provide the preconditions for electroweak baryogenesis and the generation of primordial gravitational radiation. I discuss recent developments in assessing this possibility that rely on the combination of EFT methods and non-perturbative (lattice) computations. I also discuss implications for high energy collider phenomenology and next generation gravitational wave searches.

The speaker for this event will lead the meeting remotely. All interested graduate students and faculty are invited to attend by convening in the INT seminar room (C-421).

Participants are also welcome to join via Zoom. Zoom link will be available via announcement email, or by contacting: amccoy10[at] or gsj6[at]
