Raxionbased

Raxionbased is a term that refers to a class of dark matter candidates that are based on the concept of the axion, a hypothetical particle proposed to solve the strong CP problem in quantum chromodynamics. The axion was initially introduced to explain why the neutron has an electric dipole moment that is so small. However, it was later realized that axions could also be a viable candidate for dark matter, the mysterious substance that makes up approximately 85% of the matter in the universe.

Raxionbased particles are a specific type of axion that are produced through the decay of a heavier particle, known as the raxion. The raxion is a scalar field that interacts with the Standard Model particles through a coupling constant, which determines the rate of decay. The decay of the raxion into axions can occur through various mechanisms, such as the misalignment mechanism or the decay of topological defects.

The properties of raxionbased particles depend on the specific model used to describe them. In some models, the raxion is a pseudo-Nambu-Goldstone boson, while in others, it is a fundamental scalar field. The mass of the raxionbased particle is typically in the range of microelectronvolts to kiloelectronvolts, making it a cold dark matter candidate. The interaction strength between raxionbased particles and the Standard Model particles is also model-dependent and can range from very weak to strong.

Raxionbased particles have been proposed as a solution to several astrophysical and cosmological problems, such as the baryon asymmetry of the universe and the nature of the dark matter halo. They have also been studied in the context of direct and indirect dark matter detection experiments, as well as in the context of collider searches for new physics.

In summary, raxionbased particles are a class of dark matter candidates that are based on the concept of the axion. They are produced through the decay of a heavier particle, known as the raxion, and their properties depend on the specific model used to describe them. They have been proposed as a solution to several astrophysical and cosmological problems and have been studied in the context of dark matter detection experiments and collider searches for new physics.
