SUMMARY

The axion is a hypothetical elementary particle proposed to address the strong CP problem in particle physics. It is predicted to interact through the strong and weak nuclear forces, as well as electromagnetism, via the axion-photon coupling. This coupling allows for the conversion of axions into photons, which can be experimentally observed under specific conditions. Despite its theoretical significance, the axion has not yet been detected experimentally.

PREREQUISITES
  • Understanding of the strong CP problem in quantum chromodynamics (QCD)
  • Familiarity with weak nuclear force interactions
  • Knowledge of electromagnetism and axion-photon coupling
  • Basic concepts of particle physics and theoretical particles
NEXT STEPS
  • Research the implications of the strong CP problem in quantum chromodynamics (QCD)
  • Explore experimental methods for detecting axions, such as light-shining-through-walls experiments
  • Study the role of axions in dark matter theories
  • Learn about the unification of forces, particularly the electrostrong and electroweak forces
USEFUL FOR

Particle physicists, researchers in theoretical physics, and anyone interested in the fundamental interactions of matter and the search for dark matter solutions.

Looking to confirm: Does the hypothetical axion interact through weak and strong nuclear forces?
 
Physics news on Phys.org
I don't know, so I asked ChatGPT. It said the following.

The axion is a hypothetical elementary particle that has been proposed as a solution to the strong CP problem in particle physics. It is predicted to interact through the strong and weak nuclear forces, as well as through electromagnetism.

The strong CP problem refers to the fact that quantum chromodynamics (QCD), the theory of the strong nuclear force, predicts that the strong force should violate a fundamental symmetry known as charge-parity symmetry (CP symmetry). This would lead to the appearance of an electric dipole moment in the neutron, which is not observed experimentally. The axion was proposed as a possible solution to this problem by allowing the strong force to conserve CP symmetry.

In addition to interacting through the strong and weak nuclear forces, the axion is also predicted to interact with electromagnetism through a coupling constant known as the axion-photon coupling. This interaction would allow the axion to be converted into photons and vice versa, which could potentially be observed through experiments looking for the conversion of axions into photons in strong electromagnetic fields.

Overall, the axion is a hypothetical particle that is predicted to interact through a variety of fundamental forces, including the strong and weak nuclear forces as well as electromagnetism. However, it is important to note that the axion remains a purely theoretical particle and has not yet been observed or detected experimentally.

You are right. But it will be interesting to see if someone will give a better answer. :wink:

If strong force conserves CP symmetry, will that not prevent the electrostrong force from separating into strong force and electroweak force?
 

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
