Citando:
"Particle physics is hard: the experiment which possibly detected sterile neutrinos collected 15 years' worth of data from its commissioning in 2002, but the results have only now reached pre-press publication at arXiv.
And to the non-expert, the results look indeed tiny: over 15 years, MiniBooNE detected a few hundred more electron neutrinos than were predicted in Standard Model theory.
That, however, brought the MiniBooNE team tantalisingly close to a “result” – it's a 4.8 sigma result, when “discovery” demands 5 sigma.
What's going on?
The lack of interaction makes the sterile neutrino hard to detect – so much so that a single 1990s observation by the now-decommissioned Los Alamos National Lab's Liquid Scintillator Neutrino Detector (LANL LSND) has never been replicated."
