  Explaining baryon asymmetry, dark matter and inflation are important elements
of a successful theory that extends beyond the Standard Model of particle
physics. In this paper we explore these issues within the Next-to-Minimal
Supersymmetric Standard Model (NMSSM), by studying the conditions for a
strongly first order electroweak phase transition, the abundance of the
lightest supersymmetric particle (LSP), and inflation driven by a gauge
invariant flat direction of MSSM made up of right handed squarks. We present
the regions of parameter space which can yield successful predictions for
cosmic microwave background (CMB) radiation, the observed relic density for the
neutralino LSP, and successful baryogenesis constrained by collider
measurements, such as the recent Higgs mass bound, branching ratios of rare,
flavour violating decays, and the invisible Z decay width. We also explore
where dark matter interactions with xenon nuclei would fall within current
bounds of XENON100 and the projected limits for the XENON1T and LUX
experiments.
