SUMMARY:Primordial Magnetism in CMB B-modes - Levon Pogosian (Simon Fraser
  University)

DESCRIPTION:CMB polarization B-modes induced by Faraday Rotation (FR) can 
 provide a distinctive signature of primordial magnetic fields because of t
 heir characteristic frequency dependence and because they are only weakly 
 damped on small scales\, allowing them to dominate B-modes from other sour
 ces. They also produce mode-coupling correlations of the CMB variables tha
 t can further help distinguish magnetic fields from other sources of B-mod
 es. I will present our calculation of the FR induced B-modes\, along with 
 the constraints on primordial magnetism that can be expected from upcoming
  CMB experiments.
