Probing the neutrino mass matrix in next generation neutrino oscillation experiments

Abstract

We review the current status of the neutrino mass and mixing parameters needed to reconstruct the neutrino mass matrix. A comparative study of the precision in the measurement of oscillation parameters expected from the next generation solar, atmospheric, reactor and accelerator based experiments is presented. We discuss the potential of $0\nu \beta \beta$ experiments in determining the neutrino mass hierarchy and the importance of a better ${\theta }_{12}$ measurement for it.
