Unitarity bounds for all symmetry-constrained 3HDMs

Journal of High Energy Physics, 2022
Models with three Higgs doublets (3HDM) are the source of much recent activity, for they are key components of many solutions to the problems of the Standard Model; from extra sources of CP violation to Dark Matter candidates.

Variational autoencoders for regression: recovering fully leptonic b b ¯ W + W − $$ b\overline{b}{W}^{+}{W}^{-} $$ in di-Higgs searches

Journal of High Energy Physics
The search for double Higgs production in b b ¯ W + W − $$ b\overline{b}{W}^{+}{W}^{-} $$ , where both W bosons decay to leptons, has been rehabilitated as a good option to investigate key processes within the Standard Model scalar sector at the LHC. The

Sharpening the A → Z (*) h signature of the Type-II 2HDM at the LHC through advanced Machine Learning

Journal of High Energy Physics, 2023
The A → Z (*) h decay signature has been highlighted as possibly being the first testable probe of the Standard Model (SM) Higgs boson discovered in 2012 (h) interacting with Higgs companion states, such as those existing in a 2-Higgs Doublet Model (2HDM)

Excess Higgs Production in Neutralino Decays

, 2012
The ATLAS and CMS experiments have recently claimed discovery of a Higgs boson-like particle at ~5 sigma confidence and are beginning to test the Standard Model predictions for its production and decay. In a variety of supersymmetric models, a neutralino

Anomalous gauge couplings from composite Higgs and warped extra dimensions [PDF]

, 2014
We examine trilinear and quartic anomalous gauge couplings (AGCs) generated in composite Higgs models and models with warped extra dimensions. We first revisit the SU(2)_L x U(1)_Y effective Lagrangian and derive the charged and two-photon neutral AGCs ...

CP-violation in the Weinberg 3HDM potential

Journal of High Energy Physics
We explore the phenomenology of Weinberg’s ℤ 2 × ℤ 2 symmetric three-Higgs-doublet potential, allowing for spontaneous violation of CP due to complex vacuum expectation values.

Group-theoretic restrictions on generation of CP-violation in multi-Higgs-doublet models

, 2015
It has been known since decades that imposing a symmetry group G on the scalar sector of multi-Higgs-doublet models has consequences for CP-violation.

Reconstruction of boosted and resolved multi-Higgs-boson events with symmetry-preserving attention networks

Journal of High Energy Physics
The production of multiple Higgs bosons at the CERN LHC provides a direct way to measure the trilinear and quartic Higgs self-interaction strengths as well as potential access to beyond the standard model effects that can enhance production at large ...

Boosted Event Topologies from TeV Scale Light Quark Composite Partners [PDF]

, 2015
We propose a new search strategy for quark partners which decay into a boosted Higgs and a light quark. As an example, we consider phenomenologically viable right handed up-type quark partners of mass $\sim 1$ TeV in composite pseudo-Nambu-Goldstone ...
