CMB measurements from the South Pole Telescope
South Pole Telescope Team
The most recent CMB measurements from the South Pole Telescope, combined with data from the CMB, BAO, H_0 and Sunzaey Zeldovich cluster abundances seem to indicate a cosmological preference for non-zero neutrino masses, being the mean value on the sum of the three neutrino masses
sum m? = 0.32 ± 0.11 eV
This measurement implies a quasi-degenerate neutrino mass spectrum, and it has crucial consequences for ongoing and future neutrinoless double beta decay searches.
