abstract

We scan the complete parameter space of the supersymmetric standard model extended by a gauge singlet, which is compatible with the following constraints: universal soft supersymmetry breaking terms at the GUT scale, finite running Yukawa couplings up to the GUT scale and present experimental bounds on all sparticles, Higgs scalar and top quark. The full radiative corrections to the Higgs potential due to the top/stop sector are included. We find a lower limit on the gluino mass of 160 GeV, upper limits on the lightest neutral scalar Higgs mass dependent on $m_{top}$ and the size of the soft supersymmetry breaking terms, and the possibility of a Higgs scalar as light as 10 GeV, but with reduced couplings to the Z boson.

  1. Revisiting the Electron EDM in the NMSSM

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Adding 2HDM-type two-loop diagrams to the NMSSM electron EDM calculation tightens constraints on the CP-violating phase phi4 and changes the allowed parameter space for phi3, phi4, and phi5.

  2. Loop-corrected Trilinear Higgs Self-Couplings in the NMSSM with Inverse Seesaw Mechanism

    hep-ph 2025-06 conditional novelty 5.0 of 10

    Loop corrections from inverse-seesaw neutrinos and sneutrinos can change the SM-like Higgs self-coupling by up to 10.5% and the SM-like Higgs mass by up to 4.5% in the NMSSM with inverse seesaw.
