Abstract EN
We study the NMSSM with universal Susy breaking terms (besides the Higgs sector) at the GUT scale.
Within this constrained parameter space, it is not difficult to find a Higgs boson with a mass of about 125 GeV and an enhanced cross-section in the diphoton channel.
An additional lighter Higgs boson with reduced couplings and a mass ≲ 123 GeV is potentially observable at the LHC.
The NMSSM-specific Yukawa couplings λ and κ are relatively large and tan β is small, such that λ, κ, and the top Yukawa coupling are of ?(1) at the GUT scale.
The lightest stop can be as light as 105 GeV, and the fine-tuning is modest.
WMAP constraints can be satisfied by a dominantly Higgsino-like LSP with substantial bino, wino, and singlino admixtures and a mass of ~60–90 GeV, which would potentially be detectable by XENON100.
