CP violation - theories behind it?

[RyanJ]

Hi everyone!

 

Does anyone have any information about the current theories behind the why the CP violation occured? I am interested and I can't seem to find a lot of information on the subject.

 

Cheers,

What do you mean by 'why'? Science never asks why - it only ever asks 'how'. Is this what you mean?

 

i suggest you take a look at http://en.wikipedia.org/wiki/Cp_Violation and come back to us with any questions.

I have read it

 

I should specify the question more, in what way do the current theories predict that the CP violation should occur, by that I mean are there any theories that explain why there would have been more matter produced then matter?

Any theory with CP violation predicts more matter than antimatter. The question is, is it enough? The current feeling is that the Standard Model doen't have enough CP violation to cause the baryon asymmetry we see.

 

But this is not a big problem (in my view) because we are bound to find new physics to explain it. I am sure one can generate a baryon asymmetry from other sources. For example, a heavy right handed Majorana neutrino would violate lepton number in its decays, so may be the source of the imbalance.

Ah I think I understand, its not the fact that it occurs in the first place but rather then what we currently know cannot account for the baryon asymmetry we see?

 

I do have a question though, what caused the intitial inballance in the mater:antimatter ratios?

 

Thanks for the help!
