Cosmic perturbations, baryon asymmetry and dark matter from the minimal
  supersymmetric standard model
  Scalar fields in the minimal supersymmetric standard model may have large
field values during inflation. Because of approximate global symmetry, it is
plausible that the phase directions of them are nearly massless during
inflation and obtain quantum fluctuations, which may be the origin of the
cosmic perturbations. If perturbations are produced through Q-ball formation,
baryon asymmetry and dark matter can be consistently generated. Significant
baryon and dark matter isocurvature perturbations are produced, but they are
predicted to nearly compensate each other. The lepton asymmetry is much larger
than the baryon asymmetry. The scenario predicts local non-Gaussianity of
$f_{\rm NL} = 5/3$. Implication to the mass spectrum of supersymmetric
particles is discussed.
