Flavor Ratios of Astrophysical Neutrinos: Implications for Precision Measurements
Sandip Pakvasa, Werner Rodejohann, Thomas J. Weiler
We discuss flavor-mixing probabilities and flavor ratios of high energy astrophysical neutrinos. In the first part of this paper, we expand the neutrino flavor-fluxes in terms of t…
TriMinimal Parametrization of the Neutrino Mixing Matrix
Sandip Pakvasa, Werner Rodejohann, Thomas J. Weiler
Current experimental data on neutrino mixing are very well described by TriBiMaximal mixing. Accordingly, any phenomenological parametrization of the MNSP matrix must build upon Tr…
Inverted Mass Hierarchy from Scaling in the Neutrino Mass Matrix: Low and High Energy Phenomenology
A. Blum, R. N. Mohapatra, W. Rodejohann
Best-fit values of recent global analyzes of neutrino data imply large solar neutrino mixing, vanishing U_{e3} and a non-maximal atmospheric neutrino mixing angle theta_{23}. We sh…
MiniBooNE Results and Neutrino Schemes with 2 sterile Neutrinos: Possible Mass Orderings and Observables related to Neutrino Masses
Srubabati Goswami, Werner Rodejohann
The MiniBooNE and LSND experiments are compatible with each other when two sterile neutrinos are added to the three active ones. In this case there are eight possible mass ordering…
Large and Almost Maximal Neutrino Mixing within the Type II See-Saw Mechanism
Manfred Lindner, Werner Rodejohann
Within the type II see-saw mechanism the light neutrino mass matrix is given by a sum of a direct (or triplet) mass term and the conventional (type I) see-saw term. Both versions o…
Getting Information on |U_{e3}|^2 from Neutrino-less Double Beta Decay
Alexander Merle, Werner Rodejohann
We consider the possibility to gain information on the lepton mixing matrix element |U_{e3}| from an improved experimental limit on the effective neutrino mass governing neutrino-l…
Neutrino Mixing and Neutrino Telescopes
Werner Rodejohann
Measuring flux ratios of ultra-high energy neutrinos is an alternative method to determine the neutrino mixing angles and the CP phase delta. We conduct a systematic analysis of th…
