Collider phenomenology of new neutral scalars in a flavoured multi-Higgs model

Pedro M. Ferreira, João Gonçalves, António P. Morais +3

In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signa…

Softly broken symmetries in the 2HDM -- an invariant formulation

Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1

Soft breaking of a symmetry requires an invariance of the dimension-4 part of the Lagrangian and non-trivial variation of the lower-dimensional part. However, in general, separatio…

Impact of electroweak group representation in models for and anomalies from Dark Loops

Rodrigo Capucha, Da Huang, Tomás Lopes +1

We discuss two models which are part of a class providing a common explanation for lepton flavor universality violation in decays, the dark matter (DM) problem a…

Direct detection of pseudo-Nambu-Goldstone dark matter in a two Higgs doublet plus singlet extension of the SM

Thomas Biekötter, Pedro Gabriel, María Olalla Olea-Romacho +1

We calculate the leading radiative corrections to the dark-matter-nucleon scattering in the pseudo-Nambu-Goldstone dark matter model augmented with a second Higgs doublet (S2HDM).…

P-even, CP-violating Signals in Scalar-Mediated Processes

Howard E. Haber, Venus Keus, Rui Santos

Most studies of Higgs sector CP violation focus on the detection of CP-violating neutral Higgs-fermion Yukawa couplings, which yield P-odd, CP-violating phenomena. There is some li…

Electroweak Corrections to Dark Matter Direct Detection in the Dark Singlet Phase of the N2HDM

Seraina Glaus, Margarete Mühlleitner, Jonas Müller +2

Direct detection experiments are the only way to obtain indisputable evidence of the existence of dark matter (DM) in the form of a particle. These experiments have been used to pr…

One-loop Corrections to the Higgs Boson Invisible Decay in a Complex Singlet Extension of the SM

Felix Egle, Margarete Mühlleitner, Rui Santos +1

The search for dark matter (DM) at colliders is founded on the idea of looking for something invisible. There are searches based on production and decay processes where DM may reve…
