Abstract

Constraints on neutrino masses are estimated based on future observations of the cosmic microwave background (CMB) including the B-mode polarization produced by CMB lensing using the Planck satellite, and baryon acoustic oscillations distance scale and the galaxy power spectrum from all-sky galaxy redshift survey in the BigBOSS experiment. We estimate the error in the bound on the total neutrino mass to be Δ∑ m_ν = 0.012 eV with a 68% confidence level. If the fiducial value of the total neutrino mass is ∑ m_ν= 0.06 eV, this result implies that the neutrino mass hierarchy must be normal.
