evolution of the universeThe influence of the small neutrino mass on the properties of the cosmological neutrino gas and on the evolution of the universe is estimated. The characteristics of the equilibrium neutrino gas are first calculated and the temperatures up to which to which they can be ...

Neutrino Mass and the Origin of Matter 来自 学术范 喜欢 0 阅读量: 43 作者: R Mohapatra 摘要: Discovery of neutrino masses and the possibility that the neutrinos are their own anti-particles has provided a new way to resolve a long standing puzzle of cosmology i.e. why the universe ...
The oscillation of neutronninto mirror neutronn', its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark starsn-n'transitions are suppressed. We study the structure of mixed stars and...
An earlier prediction of a cosmic ray neutron line right at the energy of the knee of the cosmic ray spectrum was based on the speculation that the electron neutrino is a tachyon whose mass is reciprocally related to the energy of the knee, $E_k$. Given the large uncertainty in $E_k$...
See-Saw Realization of the Texture Zeros in the Neutrino Mass Matrix We study the see-saw realization of seven textures of the neutrino mass matrix, which were presented by Frampton, Glashow and Marfatia. Two of them (B 1 an... A Kageyama,S Kaneko,N Shimoyama,... - 《Physics Letters ...
Next generation experiments in the three fields reach the sensitivity for the lightest mass eigenstate of $m_1<0.2eV$, which will finally answer the question if neutrino mass eigenstates are degenerate. This sensitivity is also reached by the only model-independent approach of single beta decay ...
The origin of his conception of the photon mass resides in his theory of fusion, which couples two or more free Dirac fields to pro- duce a scalar or vector Klein-Gordon equation, typically an electron-positron or neutrino-anti-neutrino duet [12–18]. In [18] the modified Maxwell ...
The effect of couplings among the dark fermion and active neutrinos are studied by putting the current cosmological data and the terrestrial neutrino experimental data. It is found that the neutrino flavor mixings evolve as well as the neutrino masses. Especially, U_{e3} develops into the non-...
