Effective 2HDM Yukawa interactions and a strong first-order electroweak phase transition

Journal of High Energy Physics
The top quark as the heaviest particle in the Standard Model (SM) defines an important mass scale for Higgs physics and the electroweak scale itself. It is therefore a well-motivated degree of freedom which could reveal the presence of new interactions ...

Constraining the Higgs trilinear coupling from an SU(2) quadruplet with bounded-from-below conditions

Journal of High Energy Physics
Integrating out a heavy scalar can cause the Higgs trilinear coupling to deviate from its Standard Model value: a good example is provided by an SU(2) quadruplet. Constraints on the full theory, however, can limit the size of the deviation.

Prospects for charged Higgs searches at the LHC

European Physical Journal C: Particles and Fields, 2017
The goal of this report is to summarize the current situation and discuss possible search strategies for charged scalars, in non-supersymmetric extensions of the Standard Model at the LHC.

Sensitivity to triple Higgs couplings via di-Higgs production in the RxSM at the (HL-)LHC and future e + e − colliders

Journal of High Energy Physics
The real Higgs singlet extension of the Standard Model (SM) without Z 2 symmetry, the RxSM, is the simplest extension of the SM that features a First Order Electroweak Phase Transition (FOEWPT) in the early universe. The FOEWPT is one of the requirements

Type-II Seesaw Higgs triplet productions and decays at the LHC

Journal of High Energy Physics
The Type-II Seesaw Model provides an attractive scenario to account for Majorana-neutrino masses. Its extended Higgs sector, if sufficiently light, can have a rich and distinctive phenomenology at the LHC while yielding automatically an essentially ...

Impact of new experimental data on the C2HDM: the strong interdependence between LHC Higgs data and the electron EDM

Journal of High Energy Physics
The complex two-Higgs doublet model (C2HDM) is one of the simplest extensions of the Standard Model with a source of CP-violation in the scalar sector. It has a $${\mathbb{Z}}_{2}$$ symmetry, softly broken by a complex coefficient. There are four ways to
