Looking to confirm: Does the hypothetical axion interact through weak and strong nuclear forces?
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.

If strong force conserves CP symmetry, will that not prevent the electrostrong force from separating into strong force and electroweak force?Demystifier said:The axion was proposed as a possible solution to this problem by allowing the strong force to conserve CP symmetry.
An axion is a hypothetical elementary particle that is predicted by some extensions of the Standard Model of particle physics. It is a neutral, low-mass particle that is thought to interact very weakly with other particles.
An axion can interact with the weak nuclear force through the process of axion-photon conversion. In this process, an axion can convert into a photon (a particle of light) in the presence of a strong magnetic field.
An axion can interact with the strong nuclear force through a process called axion-nucleon interaction. In this process, an axion can interact with the quarks inside a nucleon (proton or neutron) and exchange energy with them.
Axion interactions are important because they can help explain the properties of dark matter, which is believed to make up a large portion of the universe. Axions are one of the leading candidates for dark matter, and understanding their interactions can help us better understand the nature of this elusive substance.
There are several experiments currently underway to detect axion interactions. One method is to use powerful magnets to convert axions into photons, which can then be detected by sensitive instruments. Another method is to look for the effects of axion-nucleon interactions in high-energy particle collisions. These experiments are challenging, but could provide evidence for the existence of axions and their interactions.
