In light of the recent LHC Higgs search data, we investigate the pair production of a SM-like Higgs boson around 125 GeV in the MSSM and NMSSM. We first scan the parameter space of each model by considering various experimental constraints, and then calculate the Higgs pair production rate in the allowed parameter space. We find that in most cases the dominant contribution to the Higgs pair production comes from the gluon fusion process and the production rate can be greatly enhanced, maximally 10 times larger than the SM prediction (even for a TeV-scale stop the production rate can still be enhanced by a factor of 1.3). We also calculate the chi-square value with the current Higgs data and find that in the most favored parameter region the production rate is enhanced by a factor of 1.45 in the MSSM, while in the NMSSM the production rate can be enhanced or suppressed (\sigma_{SUSY}/\sigma_{SM} varies from 0.7 to 2.4).

    hep-ph 2025-06 conditional novelty 5.0 of 10

    In the NMSSM, interference between heavy Higgs resonances, SM top loops and stop loops can strongly distort the di-Higgs invariant mass spectrum, and a diagram-by-diagram decomposition makes these distortions interpretable.

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Double-resonant triple Higgs boson production at the LHC can be described by a single rescaling factor rho2, and projected 95% CL limits on rho2 over the (m2,m3) plane make the analysis applicable to any two-narrow-sc...
