Size of a proton as a function of relative strength of color force?

Click For Summary
SUMMARY

The discussion centers on the implications of altering the strength of the strong force on the size of protons and the stability of atomic structures. It is established that if the strong force were reduced to ten times weaker than the electromagnetic force, the proton's radius would increase significantly, potentially approaching infinity as the strong force approaches zero. The phenomenon of quark confinement remains intact as long as the coupling constant is positive, meaning that quarks will not be free even if the strong force is weakened. The relationship between the strong force and the electromagnetic force is critical in determining the stability of atomic structures, particularly in hydrogen atoms.

PREREQUISITES
  • Understanding of quantum chromodynamics (QCD)
  • Familiarity with the concepts of quark confinement and coupling constants
  • Knowledge of atomic structure, particularly the hydrogen atom
  • Basic principles of particle physics, including the roles of gluons and photons
NEXT STEPS
  • Research the implications of varying coupling constants in quantum chromodynamics
  • Study the relationship between strong and electromagnetic forces in atomic nuclei
  • Explore the concept of quark confinement and its effects on particle stability
  • Investigate the mathematical models describing the size of hadrons as a function of force strength
USEFUL FOR

Physicists, particularly those specializing in particle physics and quantum field theory, as well as students and researchers interested in the fundamental forces of nature and their effects on atomic structure.

I don't know about that...QCD works differently to EM... so you can't speak of "radiation" of the bosons... This radiation works for the EM because it has infinite range...
QCD doesn't have infinite range, and that's why we never count quarks or gluons... We just count jets of color-neutral particles...

...

We are allowing the strong coupling constant to get as weak as we please here.
