Signature of light sterile neutrinos at IceCube
Signature of light sterile neutrinos at IceCube
The MiniBooNE collaboration has recently reported evidence for a light sterile neutrino with large mixing angles, thus corroborating the measurement by LSND twenty years ago. Such a state would be directly in conflict with Planck measurement of big bang nucleosynthesis ${N}_{\mathrm{eff}}$ unless there is self-interaction in the sterile sector. Our …
