When was the quark model first proposed?
Quick Answer
In 1964, Murray Gell-Mann and independently George Zweig proposed quarks as constituents of hadrons. The idea transformed particle physics.
The Full Story
The quark model was first proposed in 1964, independently by Murray Gell-Mann and George Zweig. They suggested that hadrons such as protons and neutrons are made of smaller particles called quarks. At the time, the model seemed abstract, but it later became essential to understanding the strong force. Quarks are now known to come in six flavors and are held together by gluons in quantum chromodynamics.
