New approach to electroweak symmetry nonrestoration

M Carena, C Krause, Z Liu, Y Wang - Physical Review D, 2021 - APS
Electroweak symmetry nonrestoration up to high temperatures well above the electroweak
scale offers new alternatives for baryogenesis. We propose a new approach for electroweak …

Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing

JM Goldberg, H Liu, Y Shadmi - Journal of High Energy Physics, 2024 - Springer
A bstract We derive the dimension-8 standard-model effective theory (SMEFT) contact terms
relevant for vector-pair production at the LHC and lepton colliders. We first list the relevant …
