Symmetry violation in the early universe - a book

Click For Summary
SUMMARY

This discussion focuses on the topic of symmetry violation in the early universe, specifically addressing C, P, and T symmetry violations. The user seeks resources to understand these concepts better, particularly in relation to CP violation and its implications within the Standard Model of particle physics. Recommendations include exploring baryogenesis and leptogenesis as potential explanations for the matter-dominated universe. The discussion emphasizes the importance of academic papers available on arxiv.org for further research.

PREREQUISITES
  • Understanding of C, P, and T symmetries in physics
  • Familiarity with the Standard Model of particle physics
  • Basic knowledge of baryogenesis and leptogenesis
  • Experience with academic research, particularly in theoretical physics
NEXT STEPS
  • Research CP violation and its experimental measurements within the Standard Model
  • Study baryogenesis and leptogenesis to understand their roles in the early universe
  • Explore academic papers on arxiv.org related to symmetry violations
  • Investigate simple examples of symmetry violations in particle physics
USEFUL FOR

Physics undergraduates, researchers in theoretical physics, and anyone interested in the fundamental symmetries of the universe and their violations.

Hi there,

I've done some searching around on the forums and in the library, but I haven't found what I was looking for - some information of symmetry violation in the early universe. I know some small pieces of information but I'm currently trying to consolidate that so that I have an actual understanding (even if basic) of the theories behind C, P and T symmetry violation in the early universe. I've been so far unable to find any book that particularly addresses the issue and so I was wondering if anyone here could shed some light or point me in the right direction?

By "early universe", I simply mean at the times when these asymmetries were first theorized to occur.

I'm currently a Physics undergraduate (between my first and second year), which I mention just so anyone reading this knows what kind of level I'm at - so if I'm way above my head here, then please let me know!

Thanks for the help! :)

In general, it is easiest to understand what the three different symmetries.

Then try to understand some simple examples of violation of combinations of the symmetries.

Example, search for cp violation and the standard model. This is experimentally well measured.

Now, I think you are worried about why we are in a matter dominated universe. In which case we have to search outside of the standard model to explain this. Some of these are quite complicated, but you may want to search for some articles on;
Baryogenesis or leptogenesis

I don't have book recommendations for these last ones unfortunately. But there are many papers on arxiv.org
