models with an extended Higgs sector. The current LHC results, including both direct …

Fully differential vector-boson fusion Higgs pair production at next-to-next-to-leading order

FA Dreyer, A Karlberg - Physical Review D, 2019 - APS
We calculate the fully differential next-to-next-to-leading order (NNLO) QCD corrections to

CP violation in a model with Higgs triplets

TK Chen, CW Chiang, K Yagyu - Journal of High Energy Physics, 2023 - Springer
A bstract We discuss CP-violation in a model with a real and a complex isospin triplet Higgs
fields without introducing any symmetries except for the electroweak gauge symmetry. This …

Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories

W Su, AG Williams, M Zhang - Journal of High Energy Physics, 2021 - Springer
A bstract The electroweak phase transition can be made first order by extending the
Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the …

BSM patterns in scalar-sector coupling modifiers

C Englert, W Naskar, D Sutherland - Journal of High Energy Physics, 2023 - Springer
