We study the naturalness of electroweak symmetry breaking and baryogenesis in the next-to-minimal supersymmetric standard model (NMSSM). Our study is motivated by the recent LEP bounds on the Higgs boson mass which severely constrains the low tanβ region of the minimal supersymmetric standard model (MSSM). We show that the low tanβ region of the NMSSM is clearly favoured over the MSSM with regard to the physical Higgs boson mass, fine-tuning, and electroweak baryogenesis.

The Next-to-Minimal Supersymmetric extension of the Standard Model reviewed (2009, methodology): “There was some effort spent in systematical numerical parameter scans in order to find parameter space fulfilling the strong EWPT constraint (see for instance [189, 197, 198, 199]).”
A SM-like Higgs near 125 GeV in low energy SUSY: a comparative study for MSSM and NMSSM (2012, background): “As a result, a SM-like Higgs around 125GeV does not entail large loop contributions, which may thus ameliorate the fine-tuning problem [48–51].”
On naturalness of the MSSM and NMSSM (2012, background): “4GeV with a large λ and a small tanβ [44] or a proper H/S mixing effect [45],2 or alternatively allowing mh below the LEP bound but requiring non-standard Higgs decays to escape from the LEP search [48, 49].”
