RE: The Mystery of the Missing Antimatter - an Introduction to CPT Symmetry. (Particle Physics Series – Episode 4C)
Great post!
Good explanation of a difficult concept.
So some assymetry at the time of the big bang would explain the absence of antimatter in our visible universe?
Hello @Irelandscape. Thanks, I have been away from STEM posting for a while, I am glad to be back with this paper that took me quite a while to put together (and I am pretty proud of it as it kind of is at the frontier of my comfort zone;-))
Yup, that's right. it is an asymmetry, instants after the BB, that explains why antimatter is so scarce today. It would have been quite significant at the time. Your question rises a thought:
The CP violations we know of are too weak nowdays to explain the unbalance between matter and antimatter. Could this violation have fundamentally changed in magnitude in time? hmmm, I am not in favor of that.
But, on the other hand, I could admit that at these ultra high energies, there could be some very asymmetric processes that we haven't identified yet (for example, at the point of phase change when the gluon-quark plasma condenses into hadrons. )
It would be interesting to have the point of view of a specialist here (@lemouth) :-)
Yes, I would guess (but that's only a guess), that the assymetry so soon after the BB would have a much greater effect than later in the history of the universe?
I could be wrong about that.
Or maybe, it is still there, but we haven't identified it, or maybe it just doesn't exist (see last paragraph arguing of a sampling bias due to the flatness of the universe), or maybe we just got it terribly wrong lol!
Welcome back BTW! :-)
Cheers, am glad to be around, and to interact with you guys again!
