A New Approach to Electroweak Symmetry Non-Restoration

Learn about electroweak symmetry non-restoration in the early universe through this physics workshop presentation that explores a novel approach using an inert Higgs sector coupled with the Standard Model Higgs and extended scalar singlet sector. Discover how benchmark scenarios enable electroweak symmetry non-restoration at temperatures up to hundreds of TeV while maintaining suppressed sphaleron washout factors down to the electroweak scale. Examine the implementation of renormalization group improvements and thermal resummation in calculating effective potentials across broad energy scales and temperatures. Understand the implications for electroweak baryogenesis and early universe thermal histories, along with how this method of transmitting broken electroweak symmetry to an inert Higgs sector can be tested through Higgs physics phenomenology and electroweak precision measurements at the HL-LHC.
