Using gravitational waves to see the first second of the Universe

R Roshan, G White - arXiv preprint arXiv:2401.04388, 2024 - arxiv.org
Gravitational waves are a unique probe of the early Universe, as the Universe is transparent
to gravitational radiation right back to the beginning. In this article, we summarise detection …

Nonlinear violation in the top-Higgs sector

A Bhardwaj, C Englert, D Gonçalves, A Navarro - Physical Review D, 2023 - APS

Effective 2HDM Yukawa interactions and a strong first-order electroweak phase transition

D Azevedo, L Biermann, C Englert… - Journal of High Energy …, 2024 - Springer
A bstract The top quark as the heaviest particle in the Standard Model (SM) defines an
important mass scale for Higgs physics and the electroweak scale itself. It is therefore a well …

Resonant top pair searches at the LHC: A window to the electroweak phase transition

D Gonçalves, A Kaladharan, Y Wu - Physical Review D, 2023 - APS
