It is quite difficult to see when they are deflected by exchanging a Z-boson with a proton or neutron, but we do known that since our body contains about 20 milligrams of Potassium 40, we emit 340 million of these particles every day.
In 1969 Ray Davis began the Homestake Experiment to try and catch a few of them per year.

Bethe and Peierls showed that the probability of interaction between them and matter should be small and they were finally detected in 1956 by Cowan and Reines. In 1998 the Super-Kamiokande Experiement announced that evidence for those with non-zero mass was found. FTP, name this type of lepton with no electric charge and which was first predicted by Pauli.
