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 ...

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).

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 ...

Nullification of multi-Higgs threshold amplitudes in the standard model [PDF]
Physics Letters B, 1993 We show that nullification of all tree-order threshold amplitudes involving Higgs particles in the Standard Model occurs, provided that certain equations relating the masses of all existing elementary particles to the mass of the Higgs scalar are satisfied.

Higgs Boson Studies at the Tevatron [PDF]
, 2013 We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV$/c^2$ produced in the gluon-gluon fusion, $WH$, $ZH$, $t{\bar{t}}H$, and vector boson fusion processes, and decaying in the $H ...

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 ...

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.

CP violation in multi-Higgs supersymmetric models [PDF]
Nuclear Physics B, 1996 We consider supersymmetric extensions of the standard model with two pairs of Higgs doublets. We study the possibility of spontaneous $CP$ violation in these scenarios and present a model where the origin of $CP$ violation is soft, with all the complex phases in the Lagrangian derived from complex masses and vacuum expectation values (VEVs) of the ...
