Indeed, ever since Feynman presented his parton model in 1969, one of the most pressing problems in high-energy physics has been whether it is possible to formulate a covariant theory which will produce the quark model for slow hadrons and the parton model for fast hadrons, within the framework of the existing rules of quantum mechanics and special relativity.



Yes, it is possible. Click here!
