we have shown the predictions for the Majorana phases in the current set-up. Predictions for the Majorana phases are also important to evaluate the absolute neutrino mass parameter ($m_{\beta\beta}$) appearing in the neutrinoless double beta decay amplitude, which is shown in the right panel of figure \[fig:nhmass\]. In this figure the grey band represents the standard light neutrino contribution to $m_{\beta\beta}$ for 3$\sigma$ range of neutrino oscillation parameters in case of normal hierarchy and the dark red points superimposed over the grey band are the predicted regions in our set-up. Here we find that the predicted region entirely falls inside the correct allowed region for $m_{\beta\beta}$ in the standard three neutrino picture. In the left panel of figure \[fig:nhmass\] we present the prediction regarding sum of absolute neutrino masses as a function of lightest light neutrino $m_1$ for normal hierarchy. As can be seen here, there are enough points lying within the cosmological upper bound on sum of absolute neutrino masses mentioned earlier.

Inverted Hierarchy
------------------

Using a similar strategy, we analyse the allowed parameter space for inverted neutrino mass hierarchy. In figure \[fig:ihy1y2\], the blue dots in left panel (right panel) represent allowed points for $y_1$ vs
