Referat and Exam of Denis Kasatkin

[KasatkinMephi]

I choose the topic "Mirror world without weak interaction:
SU(3)*U(1)"

[Maxim Khlopov]

Dear Denis,
Your topic sounds like Alena's and you should agree with her about the difference in your models: e.g. you take charge symmetric case and she assumes some asymmetry in her mirror world or vice versa. In fact I don't recommend you both to take the case of three families of mirror fermions - they all should be stable without weak interaction and analysis of all the candidates for dark matter may be rather complicated. Therefore you can agree with her about difference in the number of mirror fermion families in your models either.
I look forward to a first draft of your text.
With the best regards

Good evening, Maxim Yurievich.
I will write about the second generation of quarks (C and S) in the mirror world with charge symmetry.

[Maxim Khlopov]

I look forward to a first draft.
Please specify all the physical and cosmological assumptions in your scenario
With the best regards

[KasatkinMephi]

Good afternoon. I wrote a small part of the abstract.

Здравствуйте! Я присылаю полную версию реферата

[Maxim Khlopov]

Dear Denis,
I put some comments in the attached text, but the crucial points are as follows.
You have very poor world but, please, analyze it properly. You should first calculate the frozen out abundances of c - quarks, analyze specifics of formation of mirror hadrons and freezing out of mirror muons. Then you see that the abundance of e.g. c-quarks is so low that (ccc) state can hardly be formed. You should also analyze specifics of QCD confinement in your case and the types of stable hadrons that can be formed.
To plan my work on your text I must know, whther you plan to attedn the course in the second semester
With the best regards
M.Yu.Khlopov

Здравствуйте. Я рассмотрел то, что вы мне написали.
