Abstract:

The promise of new, far more precise data from the Planck satellite and from upcoming Large Scale Structure surveys has motivated a fresh perspective on inflation. Near future constraints on non-Gaussianity (higher order statistics) of the primordial fluctuations may allow us to observationally discriminate competing particle physics realizations of inflation or put pressure on the paradigm. I'll review several of the current theoretical ideas and the variety of signals they predict in the CMB and Large Scale Structure.
