Influence of new states in searches for negative gauge-Higgs couplings

Journal of High Energy Physics
In this work, we explore how constraints based on interference effects for the negative gauge-Higgs coupling scenario are affected by new physics. Models that achieve this wrong-sign gauge-Higgs coupling inevitably have new charged Higgs states.

Phenomenological viability of orbifold models with three Higgs families

, 2005
We discuss the phenomenological viability of string multi-Higgs doublet models, namely a scenario of heterotic $Z_3$ orbifolds with two Wilson lines, which naturally predicts three supersymmetric families of matter and Higgs fields. We study the orbifold

Long-lived particle phenomenology in the 2HDM+a model

Journal of High Energy Physics, 2023
Higgs decays displaced from the primary interaction vertex represent a striking experimental signature that is actively searched for by the ATLAS, CMS and LHCb collaborations.

Precision Measurements of Higgs Couplings: Implications for New Physics Scales

, 2014
The measured properties of the recently discovered Higgs boson are in good agreement with predictions from the Standard Model. However, small deviations in the Higgs couplings may manifest themselves once the currently large uncertainties will be ...

Radiative charged-lepton mass generation in multi-Higgs doublet models

, 2014
We show that charged-lepton masses can be radiatively induced in multi-Higgs doublet models (NHDMs) through the renormalization group running of Yukawa couplings from high to low energies.

The infamous 95 GeV b b ¯ $$ \textrm{b}\overline{\textrm{b}} $$ excess at LEP: two b or not two b?

Journal of High Energy Physics
A small deviation observed around 95 GeV in the diphoton invariant mass distribution in the LHC Run 2 data has been subject to considerable attention in the past couple of years.

Dimension-8 SMEFT analysis of minimal scalar field extensions of the Standard Model

Journal of High Energy Physics, 2023
We analyze the constraints obtainable from present data using the Standard Model Effective Field Theory (SMEFT) on extensions of the Standard Model with additional electroweak singlet or triplet scalar fields.

Can multi-TeV (top and other) squarks be natural in gauge mediation?

, 2000
We investigate whether multi-TeV (1-3 TeV) squarks can be natural in models of gauge mediated SUSY breaking. The idea is that for some boundary condition of the scalar (Higgs and stop) masses, the Higgs (mass)$^2$, evaluated at the renormalization scale $

Precision Higgs width and couplings with a high energy muon collider

Journal of High Energy Physics
The interpretation of Higgs data is typically based on different assumptions about whether there can be additional decay modes of the Higgs or if any couplings can be bounded by theoretical arguments.
