SUMMARY

The nucleus is held together by the strong nuclear force, a fundamental force in the universe as defined by the standard model of particle physics. This force operates between quarks, which compose neutrons and protons, binding them together. At very short distances, the strong force is repulsive, but within the nucleus, it is predominantly attractive, counteracting the electromagnetic repulsion between protons. The strong force is mediated by the exchange of particles known as gluons, which create a gluon field among quarks.

PREREQUISITES
  • Understanding of the standard model of particle physics
  • Knowledge of quarks and their role in atomic structure
  • Familiarity with particle accelerators and their function
  • Basic concepts of fundamental forces, particularly the strong nuclear force
NEXT STEPS
  • Research the properties and behavior of gluons in particle physics
  • Explore the role of particle accelerators in detecting fundamental particles
  • Study the interactions between quarks and the implications for nuclear stability
  • Learn about the electromagnetic force and its relationship with the strong nuclear force
USEFUL FOR

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

What holds the nucleus together?

The residual strong force.

The strong nuclear force, one of the fundamental forces in the universe according to the standard model. In occurs between the quarks which make up the neutrons and protons in the nucleus, and also binds these together. At extremely small distances, it is repulsive, but at the distances in the nucleus it is generally attractive, and acts to overcome the electromagnetic force between the protons. It comes about when the quarks exchange particles called gluons with each other, thus there is a gluon 'field' between the quarks.
 
Sorry, you got there first chroot.

have they ever detected a gluon?

Billions of times.

- Warren
 
what do you mean? in what way
 
Billions of particle interactions involving gluons have been observed in dozens of different particle accelerators.

- Warren
 
but how have they proved that gluons exist
 
  • #10
Particles with a particular set of properties have appeared billions of times in particle accelerator experiments. The name given to particles with those properties is "gluon." What kind of proof do you expect there to be?

i just don't get how they would creat a strong force. it seams like magic
 
  • #12
How do electrons "create" the electromagnetic force? Are you comfortable with electrically charged particles?
