摘要: In D-term inflation models, Affleck-Dine baryogenesis produces baryonic isocurvature fluctuations. most cases the condensate is unstable with respect to collapse B-balls, which can transform baryon number perturbations into in of dark matter neutralinos. The requirement that deviation adiabatic from scale invariance not too large imposes a lower bound on magnitude general this larger than about 10(-4) times perturbation, and, for particular case late decaying 10(-2) should be observable by MAP and PLANCK.
