# Gyromagnetic Ratio: Quarks, Gluons, Antiquarks

• touqra
In summary, the gyromagnetic ratio of quarks and gluons is zero, as gluons have no magnetic moment. The ratio of quarks depends on the model and can either be 2 with a small correction, or vary depending on the model's anomalous moment. Similarly, Z bosons and neutrinos have a GR of 0 because they have no magnetic moment, while the neutron is neutral but has a magnetic moment and a GR. To determine if different particles have the same or different gyromagnetic ratios, their symmetries must be compared.

What is the gyromagnetic ratio of quarks and gluons ? Does the ratio differs between antiquarks and quarks ?

Gluons have no magnetic moment, so the gyromangetic ratio is zero.
The gyromagnetic mooment of quarks depends on the model of a quark, which is still open for speculation. For point, Dirac-like quarks the gyromagnetic ratio would equal 2, with the same type of small correction like that for an electron or muon. If quarks have a different anomalous moment (like protons do), then the GR depends on the particular model.

By the same token, Z boson and neutrino has GR = 0 since it's neutral, right ?

Not because they are neutral, but because they have no mag moment.
The neutron is neutral, but has a mag moment and a GR.

To see whether they would have the same or different gyromagnetic ration, you need to see if they obey the same or different symmetries.

What do you mean ?

## What is the gyromagnetic ratio?

The gyromagnetic ratio is a physical constant that relates the magnetic moment of a particle to its spin angular momentum.

## What are quarks?

Quarks are elementary particles that make up protons and neutrons, which in turn make up the nucleus of an atom. They have a fractional electric charge and are thought to be the building blocks of all matter.

## What are gluons?

Gluons are elementary particles that mediate the strong force, one of the four fundamental forces of nature. They are responsible for binding quarks together to form protons and neutrons.

## What are antiquarks?

Antiquarks are the antiparticles of quarks, meaning they have the opposite charge and other properties. When a quark and an antiquark combine, they form a meson, which is a type of subatomic particle.

## How is the gyromagnetic ratio related to quarks, gluons, and antiquarks?

The gyromagnetic ratio is a fundamental property of particles, including quarks, gluons, and antiquarks. It is used to study their interactions with magnetic fields and is an important factor in understanding the behavior of subatomic particles.
