abstract
We have carefully analysed the potential of future Cosmic Microwave Background (CMB) and Large Scale Structure (LSS) measurements to probe neutrino masses. We perform a Fisher matrix analysis on a 9-dimensional cosmological parameter space and find that data from the Planck CMB experiment combined with the Sloan Digital Sky Survey (SDSS) can measure a neutrino mass of 0.12 eV at 95% conf. This is almost at the level of the 0.06 eV mass suggested by current neutrino oscillation data. A future galaxy survey with an order of magnitude larger survey volume than the SDSS would allow for a neutrino mass determination of 0.03-0.05 eV (95% conf.).
