Symmetry violation in the early universe - a book

AI Thread Summary
The discussion centers on the search for information regarding symmetry violation, specifically C, P, and T symmetry, in the early universe. A physics undergraduate is seeking resources to better understand these concepts and is struggling to find a suitable book. A forum member suggests a lengthy book that covers various fields and includes some information on CP violations, although it may be challenging for beginners. They also recommend exploring articles on early universe particle physics and posting in specialized forums for more targeted assistance. The conversation emphasizes the importance of finding accessible resources to grasp complex theories in this area.

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! :)

welcome to the forum,

I have a book that is free for distribution. Its not specifically designed for early universe particle physics. By the way you can get numerous articles by typing "Early Universe particle physics." that goes into some aspects of CP violations.

the book I have is more on all forms of fields and does cover a bit on CP violations though its very lengthy and not for the faint of heart.

I would also suggest try asking in either high energy particle physics forum or possibly the QM forum. I would think you would have more luck in the former.
 
Hi, thanks for replying!

Thanks for the link, I'll post this in the High Energy part of the forum :)
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
