abstract

We fit the next-to-leading order unitarity conditions to the Two-Higgs-Doublet model with a softly broken $\mathbb{Z}_2$ symmetry. In doing so, we alleviate the existing uncertainty on how to treat higher order corrections to quartic couplings of its Higgs potential. A simplified approach to implementing the next-to-leading order unitarity conditions is presented. These new bounds are then combined with all other relevant constraints, including the complete set of LHC Run I data. The upper $95\%$ bounds we find are $4.2$ on the absolute values of the quartic couplings, and $235$ GeV ($100$ GeV) for the mass degeneracies between the heavy Higgs particles in the type I (type II) scenario. In type II, we exclude an unbroken $\mathbb{Z}_2$ symmetry with a probability of $95\%$. All fits are performed using the open-source code HEPfit.

    In the Type-II two-Higgs-doublet model, once next-to-leading-order unitarity, perturbativity and current data are imposed, the electroweak vacuum remains the global minimum among neutral vacua at tree level and one lo...

    A global fit of the Georgi-Machacek and extended Georgi-Machacek models finds that the 95 GeV diphoton and bottom-quark excesses are compatible with the 125 GeV Higgs data, while the ditau excess is not, and it sets u...

  3. Top-quark spin correlations as a tool to distinguish pseudoscalar $A \to ZH$ and scalar $H \to ZA$ signatures in $Z t \bar t$ final states at the LHC

    hep-ph 2025-02 conditional novelty 5.0 of 10

    Angular variables built from lepton directions in fully leptonic ttbar decays can distinguish A to Z H from H to Z A cascades in Z ttbar final states at the HL-LHC, reaching 6.4 to 6.5 sigma for 600/800 GeV 2HDM benchmarks.
