We demonstrate that the NMSSM can have small fine tuning and modest light stop mass while still evading all experimental constraints. For small tan(beta) [large tan(beta)], the relevant scenarios are such that there is always (often) a SM-like Higgs boson that decays to two lighter -- possibly much lighter -- pseudoscalar Higgses.

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

    hep-ph 2026-05 conditional novelty 7.0

    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.
