"Bimaximal + Democratic" type neutrino mass matrix in view of quark-lepton complementarity

High Energy Physics - Phenomenology 2009-11-11 v1

Abstract

We demonstrate that `Bimaximal + Democratic' type neutrino mass matrix can accommodate the deviation of θ\theta_\odot from its maximal value which referred in the literature as `quark-lepton complementarity' along with the other present day neutrino experimental results, namely, atmospheric, CHOOZ, neutrinoless double beta decay (ββ0ν\beta\beta_{0\nu}) and result obtained from WMAP experiment. We define a function χp\chi_p in terms of solar and atmospheric neutrino mass squared differences and solar neutrino mixing angle (obtained from different experiments and our proposed texture). The masses and mixing angles are expressed in terms of three parameters in our proposed texture. The allowed region of the texture parameters is obtained through minimization of the above function. The proposed texture crucially depends on the value of the experimental results of ββ0ν\beta\beta_{0\nu} experiment among all other above mentioned experiments. If, in future, ββ0ν\beta\beta_{0\nu} experiments, namely, MOON, EXO, GENIUS shift the lower bound on <mee><m_{ee} > at the higher side by one order, the present texture will be ruled out.
