How are the quarks in a proton or neutron held together?

SUMMARY

The strong nuclear force, mediated by gluons, is responsible for holding protons and neutrons together in the nucleus of an atom. Within protons, the interactions between the three quarks (uud) are governed by gluons, while pions serve as mediators of the residual strong force between nucleons. Understanding these interactions is crucial for grasping the fundamental forces in particle physics. The discussion highlights the distinction between gluons as force carriers at the quark level and pions at the nucleon level.

PREREQUISITES
  • Understanding of quantum chromodynamics (QCD)
  • Familiarity with the concept of fundamental forces
  • Knowledge of particle physics terminology, including quarks and gluons
  • Basic comprehension of nuclear physics and the structure of the atom
NEXT STEPS
  • Research quantum chromodynamics (QCD) and its implications in particle interactions
  • Explore the role of pions in mediating the strong nuclear force
  • Study the differences between gluons and pions in the context of nuclear forces
  • Investigate the concept of residual strong force and its effects on atomic structure
USEFUL FOR

Students and professionals in physics, particularly those focusing on particle physics, nuclear physics, and anyone interested in the fundamental forces of nature.

I've been trying to find a source for this somewhere, but I always end up with different sources explaining what holds protons and neutrons together in the nucleus of an atom. I know that the gluons hold them together, but I'm not sure exactly how they do this, and what type of transfers occur and such. If anyone could direct me to a source or give me an explanation, that would be greatly appreciated!

A forum search would likely be helpful, particularly if you start with the threads linked to at the bottom of this page.
 
Gluons are a carriers of the strong nuclear force, similarly as photons are carriers of the electromagnetic force..
So 'strong nuclear force', one of the four fundamental forces, is the simplest answer.
 
I tend to see the pions as the strong force mediators in the nuclei environment... rather than gluons...

Yes that's true when it comes to interactions between neutron to proton, proton to proton, etc, but the strong forces in the proton itself, between the uud quarks, is controlled by gluons.
 
Yup... that's why you are having something like the residual strong force (nuclear force) and the strong force (interactions of quarks and gluons).
