You're talking about asymptotic freedom. The authors are David J. Gross, a scholar at the Caffrey Center for Theoretical Physics at the University of California, Santa Barbara, H. David Politzer of the California Institute of Technology and Frank Wilczek, a 53-year-old scholar at the Massachusetts Institute of Technology. The theory of "asymptotic freedom" refers to the description of a kind of force interaction between quarks in protons. Theoretically, the interaction between quarks increases with the increase of the distance between quarks, that is, if the distance between quarks is very close, the interaction between quarks is very small, and each quark is in an almost "free" state. On the contrary, the interaction between quarks is great, and the interaction between quarks is proportional to the distance between quarks. If we use metaphor to understand this phenomenon, it is like the rubber band effect. The greater the outward tension of the rubber belt, the greater the "cohesion" inside the rubber belt, and the tension of the rubber belt is directly proportional to the "cohesion" of the rubber belt. Of course, there is a limit to any power. Rubber bands can be broken, and protons can be broken.
