Relic Vector Field and CMB Large Scale Anomalies
  We study the most general effects of relic vector fields on the inflationary
background and density perturbations. Such effects are observable if the number
of inflationary e-folds is close to the minimum requirement to solve the
horizon problem. We show that this can potentially explain two CMB large scale
anomalies: the quadrupole-octopole alignment and the quadrupole power
suppression. We discuss its effect on the parity anomaly. We also provide
analytical template for more detailed data comparison.
