Signal to background interference in at the LHC Run-II

Abdesslam Arhrib, Rachid Benbrik, Stefano Moretti +2

We investigate in the Large Hadron Collider (LHC) environment the possibility that sizeable interference effects between a {\sl heavy} charged Higgs boson signal produced via $bg\t…

The C2HDM revisited

Duarte Fontes, Margarete Mühlleitner, Jorge C. Romão +3

The complex two-Higgs doublet model is one of the simplest ways to extend the scalar sector of the Standard Model to include a new source of CP-violation. The model has been used a…

CP4 miracle: shaping Yukawa sector with CP symmetry of order four

P. M. Ferreira, Igor P. Ivanov, Enrique Jiménez +2

We explore the phenomenology of a unique three-Higgs-doublet model based on the single CP symmetry of order 4 (CP4) without any accidental symmetries. The CP4 symmetry is imposed o…

and the wrong-sign limit of the Two-Higgs-Doublet Model

Pedro M. Ferreira, Stefan Liebler, Jonas Wittbrodt

We point out the importance of the decay channels and in the wrong-sign limit of the Two-Higgs-Doublet Model (2HDM) of type II. They can be the dominant decay m…

High scale impact in alignment and decoupling in two-Higgs doublet models

Philipp Basler, Pedro M. Ferreira, Margarete Mühlleitner +1

The two-Higgs doublet model (2HDM) provides an excellent benchmark to study physics beyond the Standard Model (SM). In this work we discuss how the behaviour of the model at high e…

Probing the CP nature of the Higgs coupling in events at the LHC

S. Amor dos Santos, M. C. N. Fiolhais, R. Frederix +9

The determination of the CP nature of the Higgs coupling to top quarks is addressed in this paper, using events produced in TeV proton-proton collisio…

NLO electroweak corrections in general scalar singlet models

Raul Costa, Marco O. P. Sampaio, Rui Santos

If no new physics signals are found, in the coming years, at the Large Hadron Collider Run-2, an increase in precision of the Higgs couplings measurements will shift the dicussion…

Prospects for 2HDM charged Higgs searches

M Krawczyk, S Moretti, P Osland +2

We discuss the prospects for charged Higgs boson searches at the LHC, within the two-Higgs-doublet models (2HDM). The 2HDM is generally less constrained than the corresponding sect…

Phenomenological Comparison of Models with Extended Higgs Sectors

M. Muhlleitner, M. Sampaio, R. Santos +1

Beyond the Standard Model (SM) extensions usually include extended Higgs sectors. Models with singlet or doublet fields are the simplest ones that are compatible with the param…
