Generalized focus point and mass spectra comparison of highly natural SUGRA GUT models

, 2016
Supergravity grand unified models (SUGRA GUTs) are highly motivated and allow for a high degree of electroweak naturalness when the superpotential parameter mu~ 100-300 GeV (preferring values closer to 100 GeV).

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.

SUSY meets SMEFT: complete one-loop matching of the general MSSM

Journal of High Energy Physics
We present the complete one-loop matching of the Minimal Supersymmetric Standard Model (MSSM) onto the Standard Model Effective Field Theory (SMEFT), considering the most general case for the MSSM with conserved R-parity, which has 124 free parameters ...

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

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
