Phys. Rev. D 66, 125011 (2002) [6 pages]Cosmological limit on the neutrino massReceived 2 September 2002; published 27 December 2002 We perform a careful analysis of constraints on the neutrino mass from current cosmological data. Combining data from the cosmic microwave background and the 2dF galaxy survey yields an upper limit on the sum of the three neutrino mass eigenstates of ∑mν<~3eV (95% C.L.), without including additional priors. Including data from SNIa observations, big bang nucleosynthesis, and HST Hubble key project data on H0 tightens the limit to ∑mν<~2.5eV (95% C.L.). We also perform a Fisher matrix analysis which illustrates the cosmological parameter degeneracies affecting the determination of ∑mν. © 2002 The American Physical Society URL:
