TL;DR
This paper investigates how sterile neutrinos traveling through extra dimensions could modify neutrino oscillations, potentially explaining the LSND experimental anomaly.
Contribution
It introduces a novel mechanism where sterile neutrinos take shortcuts in extra dimensions, altering oscillation behavior and creating new resonance phenomena.
Findings
Sterile neutrinos can take shortcuts in extra dimensions.
Modified dispersion relations lead to altered oscillation patterns.
New resonance effects emerge from extra-dimensional shortcuts.
Abstract
We explore the possibility to explain the LSND result in the context of extra-dimensional theories. If sterile neutrinos take shortcuts through extra dimensions, this results in altered neutrino dispersion relations. Active-sterile neutrino oscillations thus are modified and new types of resonances occur.
