• #### The CP-symmetries of the 2HDM ﻿

(Journal article; Peer reviewed, 2020)
We discuss the three different classes of CP-symmetries that can be realized in a two-Higgs-doublet model, CP1, CP2 and CP3. We express conditions for realizing these symmetries in terms of masses and couplings of the ...
• #### CP-Violation in the $ZZZ$ and $ZWW$ vertices at $e^+e^-$ colliders in Two-Higgs-Doublet Models ﻿

(Peer reviewed; Journal article, 2016-05)
We discuss possibilities of measuring CP violation in the Two-Higgs-Doublet Model by studying effects of one-loop generated $ZZZ$ and $ZWW$ vertices. We discuss a set of CP-sensitive asymmetries for $ZZ$ and $W^+W^-$ ...
• #### Diagnosing CP properties of the 2HDM ﻿

(Peer reviewed; Journal article, 2014-01)
We have investigated a Two-Higgs-Doublet Model (2HDM), focusing on CP violation. Various scenarios with spontaneous and explicit breaking of CP have been considered. Some features of CP violation related to a choice of the ...
• #### Heavy Higgs boson decays in the alignment limit of the 2HDM ﻿

(Peer reviewed; Journal article, 2018-12)
The Standard Model (SM)-like couplings of the observed Higgs boson impose strong constraints on the structure of any extended Higgs sector. We consider the theoretical properties and the phenomenological implications of a ...
• #### Measuring CP violation in two-Higgs-doublet models in light of the LHC Higgs data ﻿

(Peer reviewed; Journal article, 2014-11)
In Two-Higgs-Doublet models, the conditions for CP violation can be ex- pressed in terms of invariants under U(2) rotations among the two SU(2) Higgs doublet fields. In order to design a strategy for measuring the invariants ...
• #### Some properties of the generic 2HDM in the alignment limit ﻿

(Peer reviewed; Journal article, 2017)
We discuss various properties of the generic two-Higgs-doublet extension of the Standard Model focusing on the region of parameter space known as the alignment limit. We emphasize that in the alignment limit in order to ...
• #### Testing the presence of CP violation in the 2HDM ﻿

(Conference object; Peer reviewed; Journal article, 2015-04-27)
We review CP properties of the Two-Higgs-Doublet model. In particular, we show that sponta- neous CP violation occurs in the parameter space on the border between regions allowing explicit CP violation and those where there ...
• #### Update on the CP-Violating Inert-Doublet Model ﻿

(Conference object; Peer reviewed; Journal article, 2012)
We have updated a recently proposed extension of the Inert Doublet Model. The extension amounts to the addition of an extra non-inert scalar doublet. The model thus offers a possibility of CP violation in the scalar sector ...
