SJTU-U. Sydney Workshop on the Electroweak Phase Transition

18 Dec 2019, 08:30 → 19 Dec 2019, 17:00 Asia/Shanghai

Tsung-Dao Lee Institute (East wing of Pao Yue-Kong Library)

Michael Ramsey-Musolf (TDLI, SJTU)

Exploring the thermal history of electroweak symmetry breaking (EWSB) is a compelling challenge at the interface of high energy physics, cosmology, and astrophysics. In the Standard Model, the EWSB transition is a smooth crossover. However, physics beyond the Standard Model may alter this history, leading to preconditions needed for electroweak baryogenesis and sources for gravitational waves. This workshop will bring together theoretical experts working on diverse aspects of electroweak symmetry-breaking at finite temperature to share ideas and develop new directions for further research in model building, finite-temperature computations, and phenomenology.
