After measuring in 2012 a relatively large value of the neutrino mixing angle θ13, the door is now open to observe for the first time a possible CP violation in the leptonic sector. The measured value of θ13 also privileges the 2nd oscillation maximum for the discovery of CP violation instead of the usually used 1st oscillation maximum. The sensitivity at this 2nd oscillation maximum is about...

In this work we present an analysis of signals from BSM physics in the IceCube neutrino telescope using the double pulse events. After more than 5 year taking data such events has not been observed, that allow us to establish new constraints in the parameters that describe BSM signals. We study which processes can be the source of such signals and the range of parameters accesible to the detector.

We analyse the neutrino oscillation phenomenology with a Dirac bulk mass in LED and comparing with the new data. Though tensions between MINOS, reactor and Miniboone data exist, different from previous studies of LED without bulk mass, we could explain Miniboone appearance. The results can also be interpreted in the framework of continuous clockwork geometry.

Neutrino mixing may be the most important clue revealing that the 3 lepton families actually represent the different but related discrete symmetries of 3 specific finite groups.

Muon neutrino disappearance measurements at NO$\nu$A suggest that maximal $\theta_{23}$ is excluded at the 2.6$\sigma$ CL. This is in mild tension with T2K data which prefer maximal mixing. We point out that the apparent departure from maximal mixing in NO$\nu$A may be a consequence of nonstandard neutrino propagation in matter. We then study such nonstandard matter effects in the next...
