Description
The recent measurement of high energy extragalactic neutrinos by the IceCube
Collaboration has opened a new window to probe non-standard neutrino properties. Among
other effects, sterile neutrino altered dispersion relations (ADRs) due to shortcuts in an extra
dimension can significantly affect astrophysical flavor ratios. We discuss an MSW-like resonant conversion arising from geodesics oscillating around the brane
in an asymmetrically warped extra dimension. We demonstrate that the second case has the
potential to suppress significantly the flux of specific flavors such as $\nu_\mu$ or $\nu_\tau$ at high energies.
