abstract

Tree-level unitarity constraints on the masses of the Higgs bosons in the general Two Higgs Doublet Model (THDM) are studied. We first consider the case where the Higgs potential is invariant under a discrete symmetry transformation, and derive strong constraints on the mass of the lightest CP-even Higgs boson ($M_h$) as a function of $\tan\beta$. We then show that the inclusion of the discrete symmetry breaking term weakens the mass bounds considerably. It is suggested that a measurement of $M_h$ and $\tan\beta$ may enable discrimination between the two Higgs potentials.

  1. Probing Boosted Light Scalars in the Type-I 2HDM

    hep-ph 2026-05 conditional novelty 7.0 of 10

    Boosted light scalars decaying to b b-bar in Type-I 2HDM can be tagged as double-b fat-jets and used with SM gauge bosons to probe heavy scalars up to 540 GeV at the HL-LHC for masses 30-70 GeV.

  2. Constraints on Loryons in a Two Higgs Doublet Model

    hep-ph 2026-01 conditional novelty 6.0 of 10

    In a two-Higgs-doublet model, neutral singlet scalar Loryons remain viable up to about 700 GeV, while charged Loryon representations are strongly constrained by unitarity and Higgs-to-diphoton measurements.

  3. Forbidden neutrinogenesis

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A neutrinophilic two-Higgs-doublet model with Dirac neutrinos can generate the observed baryon asymmetry through finite-temperature 'forbidden' leptogenesis, favoring normal neutrino mass ordering and 0 < δ_CP < π.

  4. Probing dark matter through charged Higgs pair production at future multi-TeV muon colliders: A machine-learning analysis

    hep-ph 2026-08 reject novelty 5.0 of 10

    Within the Inert Doublet Model, machine-learning selection could make charged Higgs pair production at a 10-14 TeV muon collider a 5-sigma probe of dark matter for several benchmark points.

  5. One-loop induced contributions to the rare decay of $A_0 \rightarrow h_0h_0\gamma$ in Two Higgs Doublet Models

    hep-ph 2025-01 conditional novelty 5.0 of 10

    First complete one-loop analytic calculation of A0 -> h0h0 gamma in the CP-conserving two Higgs doublet model, with benchmark decay rates and differential distributions.
