The flavourful present and future of 2HDMs at the collider energy frontier
Journal of High Energy Physics, 2022 We study the intersection of flavour and collider physics for Two-Higgs-Doublet models of Type I and II. Drawing from the flavour precision-LHC exotics search complementarity, we also provide a projection of the future sensitivity that can be achieved in

Unitarity bounds on extensions of Higgs sector
Journal of High Energy Physics, 2023 It is widely believed that extensions of the minimal Higgs sector is one of the promising directions for resolving many puzzles beyond the Standard Model (SM).

BSM patterns in scalar-sector coupling modifiers
Journal of High Energy Physics, 2023 We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson fusion Higgs pair production at present and future colliders — where the signal is a ...

The mass-degenerate SM-like Higgs and anomaly of (g − 2) μ in μ-term extended NMSSM
Journal of High Energy Physics, 2022 We chose the μ-term extended next-to-minimal supersymmetric standard model (μNMSSM) for this work, and we perform a phenomenological study based on the assumption that the observed Standard Model (SM)-like Higgs is explained by the presence of a double ...

Constraining CP4 3HDM with Top Quark Decays
Universe, 2021 CP4 3HDM is a unique three-Higgs-doublet model equipped with a higher-order CP-symmetry in the scalar and Yukawa sector. Based on a single assumption (the minimal model with a CP-symmetry of order 4 and no accidental symmetry), it leads to a remarkable ...

Pseudoscalar MSSM Higgs Production at NLO SUSY-QCD
Journal of High Energy Physics, 2023 One of the most important mechanisms at the Large Hadron Collider (LHC) for the production of the pseudoscalar Higgs boson of the Minimal Supersymmetric Standard Model (MSSM) is the loop-induced gluon fusion process gg → A.

The Higgs Decay Width in Multi-Scalar Doublet Models [PDF]
, 2007 We show that there are regions of parameter space in multi-scalar doublet models where, in the first few hundred inverse femtobarns of data, the new charged and neutral scalars are not directly observable at the LHC and yet the Higgs decay rate to b bbar

3HDM with ∆(27) symmetry and its phenomenological consequences
Journal of High Energy Physics, 2023 We perform a comprehensive analysis of a version of the 3-Higgs doublet model whose scalar potential is invariant under a global ∆(27) discrete symmetry and where the three scalar doublets are chosen to transform as a triplet under this discrete group ...

The invariant space of multi-Higgs doublet models [PDF]
Journal of High Energy Physics, 2021 Abstract In a model with more than one scalar doublet, the parameter space encloses both physical and unphysical information. Invariant theory provides a detailed description of the counting and characterization of the physical parameter space. The Hilbert series for the 3HDM is computed for the first time using partition analysis,
