The status of the evaluation of the MSSM Higgs sector is reviewed. The phenomenological impact of recently obtained corrections is discussed. In particular it is shown that the upper bound on m_h within the MSSM is shifted upwards. Consequently, lower limits on tan beta obtained by confronting the upper bound as function of tan beta with the lower bound on m_h from Higgs searches are significantly weakened. Furthermore, the region in the M_A-tan beta-plane where the coupling of the lightest Higgs boson to down-type fermions is suppressed is modified. The presently not calculated higher-order corrections to the Higgs-boson mass matrix are estimated to shift the mass of the lightest Higgs boson by up to 3 GeV.

    hep-ph 2025-07 conditional novelty 6.0 of 10

    First full one-loop computation of e+e- -> h1 Z in the cNMSSM: corrections near -10%, nearly identical to the MSSM once the light Higgs mass is fixed.

    A dedicated boosted-jet category in HH→bbγγ is projected to narrow the κ2V constraint to [-0.4, 2.6] at 95% CL and improve heavy-resonance limits by 1–2x at 308 fb⁻¹.
