We analyze with the Bayesian method the solar and KamLAND neutrino data in terms of neutrino oscillations. We show that Bayesian credible regions with a flat prior in the tan^2(theta12)--(Delta m^2)_21 plane strongly support the LMA solution, in agreement with the usual chi-square analysis. Other reasonable priors are considered in order to test the stability of the LMA solution. We show that priors which favor small or large values of the mixing angle lead to minor changes of the allowed LMA region, affecting mainly its large tan^2(theta12) part.
We investigate the potential of 3 kiloTon-years(kTy) of KamLAND data to further constrain the $Delta m^2$ and $tan^2theta$ values compared to those presently allowed by existing KamLAND and global solar data. We study the extent, dependence and chara
In this work we have re-investigated two different kinds of texture zero ansatz of the low energy neutrino mass matrix in view of the Dark-Large-Mixing-Angle (DLMA) solution of the solar neutrino problem which can arise in the presence of non-standar
We analyze the existing solar neutrino experiment data and show the allowed regions. The result from SNOs salt phase itself restricts quite a lot the allowed regions area. Reactor neutrinos play an important role in determining oscillation parameters
We analyze the effect of the Dark-large mixing angle (DLMA) solution on the effective Majorana mass ($m_{betabeta}$) governing neutrino-less double beta decay ($0 ubetabeta$) in the presence of a sterile neutrino. We consider the 3+1 picture, compris
Neutrino-neutrino interactions in dense neutrino streams, like those emitted by a core-collapse supernova, can lead to self-induced neutrino flavor
