Investigating the Hybrid Textures of Neutrino Mass Matrix for Near Maximal Atmospheric Neutrino Mixing

Figure 5

Correlation plots for textures ((a), (c)) and ((b), (d)) with IO for 1TEE at 3 CL. The symbols have their usual meaning. In (a) and (b), colored horizontal line indicates the upper limit on effective neutrino mass term (i.e., ) at 90 (<2σ)% CL, given in KamLAND-Zen experiment [7]. In (c) and (d), we have shown the upper limit on reactor mixing angle .
