Neutrino mixing matrices with relatively large θ 13 and with texture one-zero

The recent T2K, MINOS and Double Chooz oscillation data hint at a relatively large θ13, which can be accommodated by some general modification of the tribimaximal/bimaximal/democratic mixing matrices. Using such matrices we analyze several Majorana mass matrices with texture one-zero and show whether they satisfy the normal or the inverted mass hierarchy and are phenomenologically viable or not.

Can nonstandard interactions jeopardize the hierarchy sensitivity of DUNE

We study the effect of non-standard interactions (NSIs) on the propagation of neutrinos through the Earth matter and how it affects the hierarchy sensitivity of the DUNE experiment. We emphasize on the special case when the diagonal NSI parameter

. Moreover the unknown magnitude and phases of the off-diagonal NSI parameters can give rise to additional degeneracies. Overall, given the current model independent limits on NSI parameters, the hierarchy sensitivity of DUNE can get seriously impacted. However, a more precise knowledge on the NSI parameters, specially
