We present the public code ScannerS-2 that performs parameter scans and checks parameter points in theories beyond the Standard Model (BSM) with extended scalar sectors. ScannerS incorporates theoretical and experimental constraints from many different sources in order to judge whether a parameter point is allowed or excluded at approximately 95% CL. The BSM models implemented in ScannerS include many popular BSM models such as singlet extensions, different versions of the Two-Higgs-Doublet Model, or the different phases of the Next-to Two-Higgs-Doublet Model. The ScannerS framework allows straightforward extensions by additional constraints and BSM models.

    hep-ph 2025-06 conditional novelty 7.0 of 10

    In the inverted Type-I 2HDM, one-step and two-step strong first-order electroweak phase transitions live in largely separate parameter regions, and LISA-detectable gravitational wave signals come predominantly from th...

  2. Full Next-To Leading-Order Electroweak and QCD Corrections to the Relic Density in the CxSM

    hep-ph 2026-07 conditional novelty 6.0 of 10

    NLO QCD and electroweak corrections to the CxSM dark-matter relic density are computed and released in the public code RelExt@NLO; the corrections shift the allowed parameter region in both directions.

  3. TRSMScans

    hep-ph 2026-07 accept novelty 6.0 of 10

    TRSMScans is an automated zoom-optimization scanner that computes maximal allowed rates for asymmetric scalar production and decay chains in the TRSM (and potentially other ScannerS models) under all theoretical and e...

    hep-ph 2026-07 accept novelty 6.0 of 10

    In the Normal 2HDM, SFOEWPTs are single-step and alignment-favoring across all four Yukawa types, yet Parwani versus Arnold–Espinosa resummation changes the viable heavy-mass range from ~1.6 TeV to ≲800 GeV and leaves...

  5. Interpreting Light Scalar Excesses and Heavy Scalar Cascades in the $\mu$-Term Extended NMSSM

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    Viable μNMSSM regions can fit the 95 GeV diphoton/bb anomalies and produce H→hhs and A2→hA1→4b cascades near the 650 and (600,400) GeV CMS structures.

  6. Perturbative unitarity for models with singlet and doublet scalars

    hep-ph 2025-10 conditional novelty 6.0 of 10

    Arbitrary scalar extensions with doublets, neutral singlets, and charged singlets now have complete analytic perturbative-unitarity bounds, automated by the BounDS Mathematica notebook.

  7. Vacuum Instability and False Vacuum Decay Induced by Domain Walls in the N2HDM

    hep-ph 2025-06 conditional novelty 6.0 of 10

    Domain walls in the N2HDM can erase the barrier around the electroweak vacuum, making long-lived metastable vacua decay classically and excluding parameter points previously considered viable.

  8. Low mass scalars at $e^+e^-$ colliders

    hep-ph 2026-04 unverdicted novelty 2.0 of 10

    The paper summarizes new developments in models and experimental searches for low-mass scalars at Higgs factories since prior reviews.
