Description
The motivations for the Next-to-Minimal Supersymmetric Standard Model
(NMSSM) are reviewed, and possible unconventional signals for Higgs and
sparticle production at the LHC are discussed. In the presence of a
light pseudoscalar, the SM-like Higgs scalar can decay dominantly into a
4-tau final state. In the fully constrained NMSSM with mSUGRA-like soft
SUSY breaking terms, the correct dark matter relic density is obtained
for a singlino-like LSP and a stau NLSP, which modifies considerably all
sparticle decay chains.
Summary
We review resent results on NMSSM specific Higgs and sparticle searches at
colliders.
