UCL HEP Seminars & Vivas

Seminars are generally held at 16:00 on Fridays in room A1 on the top floor of the Physics Department or — in the unlikely event of a global pandemic — online via Microsoft Teams or Zoom.

A calendar of all seminars in the Physics Department is available on the Physics Events Calendar page.

Please send suggestions for topics and/or speakers to Matteo Agostini, Lucy Bailey, Lucian Harland-Lang, Andreas Korn and Margot MacMahon.

SPECIAL SEMINAR:: Was There an Electroweak Phase Transition?

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 generating the cosmic matter-antimatter asymmetry through electroweak baryogenesis and provide a source of primordial gravitational radiation. I discuss recent theoretical developments in assessing this possibility and the implications for high energy collider phenomenology and next generation gravitational wave searches.
