摘要Considering the mass splitting between three active neutrinos, we represent the new constraints on the sum of neutrino mass Sigma m(nu) by updating the anisotropic analysis of the Baryon Acoustic Oscillation (BAO) scale in the CMASS and LOWZ galaxy samples from Data Release 12 of the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS DR12). Combining the BAO data of 6dFGS, MGS, LOWZ and CMASS with Planck 2015 data of temperature anisotropy and polarizations of the Cosmic Microwave Background (CMB), we find that the 95 % C.L. upper bounds on Sigma m(nu) refer to Sigma m(nu, NH) < 0.18 eV for the normal hierarchy (NH), Sigma m(nu, IH) < 0.20 eV for the inverted hierarchy (IH) and Sigma m(nu, DH) < 0.15 eV for the degenerate hierarchy (DH), respectively, and the normal hierarchy is slightly preferred over the inverted one (Delta chi(2) chi(2)(NH) - chi(2)(IH) similar or equal to -3.4). In addition, the additional relativistic degrees of freedom and massive sterile neutrinos are neither favored at present.
