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.

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 ...

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 ...

Signals of non-minimal higgs sectors at future colliders [PDF]

, 1996
This thesis concerns the study of extended Higgs sectors at future colliders. Such studies are well motivated since enlarged Higgs models are a necessity in many extensions of the Standard Model (SM), although these structures may be considered purely in

How do top teams succeed? Factors that contribute to successful senior management team performance

, 2006
For many years consultancy assignments on team-working have been growing in popularity as a means of building competitive advantage. However, this popularity has not been underpinned by rigorous, organisationally-based research (West and Slater, 1995 ...

Probing a long-lived pseudoscalar in type-I 2HDM with displaced vertices and jets at the LHC

Journal of High Energy Physics
In the type-I two-Higgs-doublet model, the pseudoscalar A can act as a long-lived particle (LLP) for sufficiently large values of tan β. At the LHC, the A particles are predominantly produced in pairs through pp → W ∗/Z ∗ → H ± /H A, with subsequent ...

Loop induced H ± W ∓ Z vertices in the general two Higgs doublet model with CP violation

Journal of High Energy Physics
Understanding symmetry of extended Higgs models helps to construct the theory beyond the standard model and gives important insights for testing these models by experiments.
