Abstract

In this paper, we discuss neutrino mass eigenvalues for four flavor neutrino\nmixing. An extra mass states, in four flavor mixing and possible various\ncombination of CP violating Majorana phases effects the neutrino mass\neigenvalues. We have considered the effective Majorana mass m_e, related for\n ,\(\β\β\)_{0\ν ,} decay. In calculation, we consider two\ndifferent neutrino mass orders, normal and inverted. We find the limits for\nneutrino mass eigenvalue m_i in the different neutrino mass spectrum and the\nsum of all four neutrino masses is\n text\Σ text ensuremath\≡m₁+m₂+m₃+m₄>1.3 ,eV ,\nwhich is relevant for cosmological observations and explain the different\nneutrino oscillations data.\n
