Which force is responsible for the existence of neutrinos in beta decay?
Quick Answer
The weak nuclear force produces and interacts with neutrinos in beta decay. Neutrinos were proposed to conserve energy and momentum in radioactive processes.
The Full Story
Neutrinos are closely tied to the weak interaction. They appear in beta decay when a nucleus changes one type of nucleon into another, carrying away energy, momentum and angular momentum. Wolfgang Pauli proposed the neutrino in 1930, and it was first detected in 1956 by Clyde Cowan and Frederick Reines. Neutrinos interact only through the weak force and gravity, which is why they are so difficult to detect. Their study has become a major part of modern particle and astrophysics.
