Determining Min. Charge States of Yukawa's Particle & Why Gluons are Massless

In summary, the conversation discusses the minimum number of charge states of yukawa's particle by considering interactions between protons and neutrons. It also questions why the interquark force is of finite range but appears to be carried by massless exchange particles. There is a suggestion that the charges of the Y particles must equal all possible proton-neutron charge differences, and that the q-q force has a confining potential that does not vanish as r-->large, but instead goes like V~r for large r.

Hi,
i am kind stuck on this question as i don't know what equation to use. doesn't seem to be in any books.

By considering possible interactions between protons and neutrons, determine the minimum number of charge states of yukawa's particle.

Also why is the interquark force of finite range but appears to be carried by massless exchange particles(gluons).

1. The charges of the Y particles have to equal all possible proton-neutron charge differences.
2. The q-q force appears to have a "confining" potential that does not vanish as r-->large.
It seems to go like V~r for large r.
 

1. What is Yukawa's particle?

Yukawa's particle, also known as the Higgs boson, is an elementary particle that is theorized to give other particles their mass through the Higgs field.

2. How is the minimum charge state of Yukawa's particle determined?

The minimum charge state of Yukawa's particle is determined through experiments, such as the Large Hadron Collider, which collide particles at high energies to observe the presence of the Higgs boson and its charge state.

3. Why are gluons considered massless?

Gluons are considered massless because they do not interact with the Higgs field, which is responsible for giving particles their mass. They also do not have a charge, making them unaffected by the electromagnetic field.

4. How does the masslessness of gluons affect the behavior of the strong nuclear force?

The masslessness of gluons allows them to travel at the speed of light and interact with each other without any resistance. This results in the strong nuclear force, which is responsible for binding quarks together to form protons and neutrons, being a long-range force.

5. Are there any implications of gluons being massless in other areas of physics?

Yes, the masslessness of gluons has implications in fields such as quantum chromodynamics and the Standard Model of particle physics. It also has implications in the study of the early universe and the formation of matter after the Big Bang.
