| Abstract | The three-year Wilkinson Microwave Anisotropy Probe observations, combined with other cosmological observations from galaxy clustering and type Ia supernovae, favour a non-vanishing running of the primordial spectral index independent of the low cosmic microwave background multipoles. Motivated by this feature we study a cosmological constraint on the neutrino mass, which is strongly dependent on what prior we adopt for the spectral shape of primordial fluctuations, taking possible running into account. As a result we find a more stringent constraint on the sum of the three neutrino masses, m(nu) < 0.76 eV (2 sigma), compared with m(nu) < 0.90 eV (2 sigma) for the case where a power law prior is adopted for the primordial spectral shape. |
