The role of exotic resonances in the early universe

[Loren Booda]

Did the era prior to decoupling experience abundant particle resonances that are now rare? Were there then composite and stable entities, like atoms, constructed from these particles? What would the lifetimes of the resonances be, given that their optimum surrounding conditions remained constant? What correlations can be drawn between the particle physics of then and now?

Thats a good question, and its a hard one b/c the physics in that epoch is all over the place as the temperature goes up. Different regimes will feel different exotic processes.

We have a fairly good understanding of how things behave in certain intervals, (some in the far past, some in the close to reionization epochs) but not the whole things.

In general its the dominant processes that people have somewhat of a handle on, b/c often they leave measurable consequences somewhere down the chain. But I mean, some of the regimes are active research areas today even in particle physics (like quark-gluon plasmas), its obviously very difficult to get a full grasp of the consequences since we don't have a time machine.

The role of exotic resonances in the early universe is a topic of great interest and ongoing research in the field of cosmology. These resonances refer to particles that have short lifetimes and are created and destroyed rapidly in the extreme conditions of the early universe.

It is believed that the era prior to decoupling, when the universe was only a few seconds old, did experience a high abundance of particle resonances. This is because the universe was much hotter and denser at that time, allowing for the creation of exotic particles that cannot be produced in the current, relatively cooler state of the universe. As the universe expanded and cooled, these particles became rarer and eventually stopped being produced altogether.

It is possible that composite and stable entities, similar to atoms, were formed from these exotic particles in the early universe. However, the extreme conditions and rapid changes in the universe at that time make it difficult to accurately predict the exact composition and behavior of these entities.

The lifetimes of these resonances would depend on the surrounding conditions, such as temperature and density, which were constantly changing in the early universe. However, it is likely that their lifetimes would have been very short, on the order of microseconds or even less.

There are many correlations that can be drawn between the particle physics of the early universe and the current state of the universe. For example, the existence of dark matter, which is believed to make up a significant portion of the universe's mass, could potentially be explained by the presence of exotic particles in the early universe. Additionally, the study of exotic resonances in the early universe can help us better understand the fundamental laws of physics and the behavior of particles under extreme conditions.

In conclusion, the role of exotic resonances in the early universe is a fascinating and important area of research that can provide valuable insights into the origin and evolution of our universe. While the exact nature and behavior of these resonances may never be fully understood, studying them can help us gain a deeper understanding of the fundamental laws of physics and the nature of our universe.
