"CMB lensing extraction"

CMB lensing extraction may provide a very precise handle on some cosmological parameters which only mildly affect the primaries anisotropies (like the dark energy equation of state parameter, or the neutrino masses). I will present a basic introduction on the techniques proposed so far for carrying such an analysis in the future (Planck and post-Planck). At the end of the talk, I will discuss the particular issue of contamination of the lensing extraction by primordial non-gaussianities generated in the early universe.
