Neutrinos
Most muon neutrinos oscillate to tau neutrinos. However, 3.4
GeV threshold to produce taus in the detector !!!

Sterile neutrino suggestions
LSND
Evidence for neutrino oscillations from the observation of ¯νe appearance in a ¯νμ beam, Phys Rev D, Nov 2001
Supposedly needs sterile neutrinos to explain 3.8σ excess from Fig 24 which looks completely unimpressive.
MiniBooNE https://www-boone.fnal.gov/
In 2013, also reported a 2.8σ excess (Fig. 1),

DONUT (Direct observation of the nu tau, E872) was an experiment at Fermilab, using 800
GeV protons on tungsten, dedicated to the search for tau neutrino interactions.
