Signatures of heavy sterile neutrinos at long baseline experiments
Signatures of heavy sterile neutrinos at long baseline experiments
Sterile neutrinos with masses $\ensuremath{\sim}0.1\text{ }\text{ }\mathrm{eV}$ or higher, allowed with the current oscillation data, can potentially play an important role in astrophysics and cosmology. We explore possible signatures of such sterile neutrinos at long baseline experiments. We determine the neutrino conversion probabilities analytically in a 4-neutrino framework, including matter …
