Testing CP properties of extra Higgs states at the HL-LHC [PDF]
Journal of High Energy Physics, 2020 Extra Higgs states appear in various scenarios beyond the current Standard Model of elementary particles. If discovered at the LHC or future colliders, the question will arise whether CP is violated or conserved in the extended scalar sector.

Entanglement suppression, enhanced symmetry, and a standard-model-like Higgs boson [PDF]
Physical Review D, 2023 We study information-theoretic properties of scalar models containing two Higgs doublets $\Phi_a$, where $a=1,2$ is the flavor quantum number. Considering the 2-to-2 scattering $\Phi_a \Phi_b \to \Phi_c \Phi_d$ as a two-qubit system in the flavor ...

Higgs properties in a softly broken Inert Doublet Model [PDF]
, 2013 A bstractWe consider a model for the Higgs sector with two scalar doublets and a softly broken $ {{\mathbb{Z}}_2} $ symmetry, the Stealth Doublet Model. This model can be seen as a generalization of the Inert Doublet Model.

The general Two-Higgs Doublet Model in a gauge-invariant form
Journal of High Energy Physics, 2022 In the general Two-Higgs Doublet Model it has been shown that the Higgs potential can be expressed in terms of gauge-independent quantities that transform covariantly under unitary mixing of the doublets.

Proca-Higgs balls and stars in a UV completion for Proca self-interactions [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 We consider a Proca-Higgs model wherein a complex vector field gains mass via spontaneous symmetry breaking, by coupling to a real scalar field with a Higgs-type potential.

Exploring wrong sign scenarios in the Yukawa-Aligned 2HDM
Journal of High Energy Physics, 2023 We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered Higgs boson in the Yukawa-aligned two Higgs doublet model. In the WS scenario, Yukawa couplings for down-type quarks and/or charged leptons have an opposite sign as compared to

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

Critical points in Palatini Higgs inflation with small non-minimal coupling [PDF]
Journal of High Energy Physics, 2023 We investigate inflation driven by the Higgs boson in the Palatini formulation of General Relativity. Our analysis primarily focuses on a small non-minimal coupling of the Higgs field to gravity in the range 0 < ξ ≲ 1.
