Description
Particle Physics teaches us that neutrinos do have a mass and therefore contribute to the matter energy budget in the universe. After reviewing by which mechanisms cosmology constrain the fraction of HDM, I will review the current bounds and extrapolate the results to the soon-to-come PLANCK data. In particular I will show how CMB lensing reconstruction can be performed for the first time with PLANCK, tightening even more the expected sensitivity to neutrino masses.
