 Title: Cosmic Perturbations and Baryon Asymmetry from a Rotating Field\nS
 peaker: Taegyu Lee\nAbstract:\nIn the Affleck–Dine mechanism\, the bary
 on asymmetry is generated by the rotational motion of a scalar field along
  a flat direction. We study a concrete SUSY flat direction in which the sa
 me scalar field can generate baryon number as well as work as a curvaton. 
 This well-motivated setup can naturally lead to a slightly red tilted spec
 trum with ns<1 which is usually non-trivial since it needs some fine tunin
 g in the curvature of the potential. In this set up\, we determine the reg
 ion of parameter space consistent with the observed adiabatic curvature pe
 rturbations. We also show that the observed baryon asymmetry can be genera
 ted while keeping baryon isocurvature consistent with Planck measurement. 
 Finally\, we discuss how dark matter can be incorporated consistently with
 in the same framework.\n\n\nhttps://indico.kias.re.kr/event/425/
