Multi-Higgs models with CP symmetries of increasingly high order [PDF]
Physical Review D, 2018 When building CP-symmetric models beyond the Standard Model, one can impose CP-symmetry of higher order. This means that one needs to apply the CP-transformation more than two times to get the identity transformation, but still the model is perfectly CP ...

CP-odd invariants for multi-Higgs models and applications with discrete symmetry [PDF]
, 2017 CP-odd invariants are useful for studying the CP properties of Lagrangians in any basis. We explain how to build basis invariants for the scalar sector, and how to distinguish CP-odd invariants from CP-even invariants. Up to a certain order, we use these

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 ...

A simple method to detect spontaneous CP violation in multi-Higgs models [PDF]
, 2017 A bstractFor models with several Higgs doublets we present an alternative method to the one proposed by Branco, Gerard and Grimus, in 1984, to check whether or not CP is spontaneously violated in the Higgs potential.

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).

Review of LHC experimental results on low mass bosons in multi Higgs models [PDF]
, 2016 A bstractA variety of searches have been performed at the LHC using Run I data, looking for decays of the discovered Higgs boson, h125, decaying to a pair of low mass bosons, with mass in the range 2mμ−mh125/2≃62$$ 2{m}_{\mu }-{m}_{h_{125}}/2\simeq 62 $$

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

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 ...

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 ...
