CP violation in H^\pm \to W^\pm Z: A physical approach for the 2HDM

Wafaa Khater, Odd Magne Ogreid, Per Osland +1

We investigate CP violation in the process H^\pm \to W^\pm Z within the framework of the two-Higgs-Doublet model (2HDM). Amplitudes are expressed transparently in terms of physical…

Systematic analysis of 3HDM symmetries

A. Kunčinas, P. Osland, M. N. Rebelo

Symmetries play a crucial role in shaping the structure and predictions of multi-Higgs-doublet models. In three-Higgs-doublet models considerable effort has been put into classifyi…

High-Dimensional Unfolding in Large Backgrounds

Alexandre Falcão, Adam Takacs

We propose new methodologies in multi-dimensional unfolding in dense environments, and show that incorporating auxiliary observables can significantly improve performance. Our appr…

Gravitational Wave Signals in a Promising Realization of SO(10) Unification

Injun Jeong, Jörn Kersten, Stefano Scopel +1

We investigate gravitational wave signals in a non-supersymmetric grand unified model where the group is broken in two steps to the Standard Model gauge group. We calculat…

Gravitational waves from a first-order phase transition of the inflaton

Jörn Kersten, Seong Chan Park, Yeji Park +2

We explore the production of gravitational waves (GW) resulting from a first-order phase transition (FOPT) in a non-minimally coupled `Dark Higgs Inflation' model. Utilizing a dark…
