Question: who discovered the Neutrinos, and how did they come about this discovery?

Hi
So the story of neutrino is very interesting, it happened when people took a look at a nuclear process called beta decay. Before making this experiment, everybody thought the beta decay was the process where a neutron decayed in a proton and an electron. One particle becoming 2 particles basically. But the energy of the electron could not match the predictions when only 2 particles were assumed. So Pauli (a famous scientist), had to admit that he couldn’t explain this process unless he assumed there was something else (the neutrino!). This was in 1930, and scientists had to wait till 1956 to really see a neutrino. The process used was basically the inverse as the one that used Pauli, what we call the beta-capture (one proton and a neutrino becomes a neutron and electron)! To finish the story the scientists (Cowan and Reines) who discovered the neutrino only received a Nobel price in 1995!
