Through Electric charge, Neutrino and Speed of light
Discovery
The muon neutrino or "neutretto" was hypothesized by several physicists in the 1940s. The first paper on it may be Shoichi Sakata and Takesi Inoue's two-meson theory of 1942, which also involved two neutrinos. In 1962 Leon M. Lederman, Melvin Schwartz and Jack Steinberger proved the existence of the muon neutrino in an experiment at the Brookhaven National Laboratory. This earned them the 1988 Nobel Prize.

Apparent speed anomaly
In September 2011 OPERA researchers reported that muon neutrinos were apparently traveling at faster than the speed of light. This result was confirmed in a second experiment in November 2011. These results were viewed skeptically by the scientific community at large, and more experiments investigated the anomaly. In March 2012 the ICARUS team published results directly contradicting the results of OPERA.
Later, in July 2012, the apparent anomalous super-luminous propagation of neutrinos was traced to a faulty element of the fibre optic timing system in Gran Sasso. After it was corrected the neutrinos appeared to travel with the speed of light within the errors of the experiment.
