The positive electron
Anderson found 15 cosmic-ray tracks of positive particles far lighter than a proton, with charge probably equal to the proton's: the positron.
As reported in: Anderson (1933). The Positive Electron. Physical Review. doi:10.1103/PhysRev.43.491
Free neutrino detected
Cowan, Reines and colleagues reported detection of the free neutrino.
As reported in: Cowan, Reines, Harrison et al. (1956). Detection of the Free Neutrino: a Confirmation. Science. doi:10.1126/science.124.3212.103

Neutrinos oscillate
The Super-Kamiokande collaboration found a zenith-angle-dependent deficit of atmospheric muon neutrinos, evidence for neutrino oscillation.
As reported in: Fukuda, Hayakawa, Ichihara et al. (1998). Evidence for Oscillation of Atmospheric Neutrinos. Physical Review Letters. doi:10.1103/PhysRevLett.81.1562
