Absolute value of the effective neutrino mass against the mass of the lightest neutrino for both the normal and inverted mass hierarchy and for all possible values of the phases and defined in (15). The best-fit values [5] are used for the oscillation parameters (see (8)). The cosmological upper limit for , derived from the Planck satellite measurements [6], is also given.
