abstract

We examine an extension of the SM Higgs sector by a Higgs triplet taking into consideration the Higgs-like particle discovery at the LHC with mass around 125 GeV. We evaluate the bounds on the scalar potential through the unitarity of the scattering-matrix. Considering with and without $\Z_2$-symmetry on the extra triplet, we derive constraints on the parameter space. We identify the region of the parameter space that corresponds to the stability and metastability of the electroweak vacuum. We also show that at large field values the scalar potential of this model is suitable to explain inflation.

  1. Unveiling the inert Triplet desert region with a pNGB Dark Matter and its Gravitational Wave signatures

    hep-ph 2025-05 conditional novelty 6.0 of 10

    A two-component dark matter model combining an inert scalar triplet with a pseudo-Goldstone singlet revives the sub-TeV triplet desert region and predicts gravitational waves detectable by LISA, BBO, and DECIGO.

  2. Dark clouds to silver linings over the hyperchargeless scalar triplets

    hep-ph 2025-05 conditional novelty 5.0 of 10

    Under current constraints, the inert triplet model is insufficient for dark matter and for a first-order phase transition, while the non-inert triplet model retains a narrow 150 to 275 GeV window for a strong two-step...

  3. Probing Fermion-Portal Scalar Dark Matter through Charged Vector-Like Fermions at Future Muon Colliders

    hep-ph 2026-07 conditional novelty 4.0 of 10

    Yukawa-driven t/u-channel and co-annihilation processes allow fermion-portal scalar dark matter to match the relic density while remaining consistent with direct detection, and muon colliders can probe the lightest ch...
