[EKozlova_MEPhI]

Здравствуйте, Максим Юрьевич!
Я выбрала тему "Mirror world without weak interaction: SU(3)*U(1)".

[Maxim Khlopov]

Thank you. I look forward to your first draft

Добрый вечер, Максим Юрьевич!
Прикладываю черновик черновика реферата.
В дальнейшем планирую рассмотреть модель совместного существования реального и зеркального миров и более подробно рассмотреть рехитинг.
С уважением, Екатерина.

Dear Ekaterina,
My comments are in the attached file. In the case of charged symmetric mirror world (with equal amounts of particles and antiparticles) I doubt that you can get sufficient mirror density to explain the dominant form of dark matter, but even in this case you should specify all the stable species formed by your stable quarks and leptons, calculate their abundance and describe their cosmological evolution. The list of possible reactions would be very interesting in your model.
I look forward to the next version
With the best regards

Dear Ekaterina,
For the moment, I cannot put you more than 4 as an intermediate mark, if you don't put a second draft of your referat in reply to this post until tomorrow evening.

Добрый день, Максим Юрьевич!
Прошу прощения за столь долгую задержку со второй версией.

По поводу вашего вопроса о втором семестре: сдавать курс не планирую, но, если вы не против, буду вольнослушателем.
С уважением, Екатерина.

[Maxim Khlopov]

Dear Ekaterina,
My comments are in the attached file. You should either take into account all stable species from all the 3 families, or add the assumption that you have only 1 family in mirror world. Then the picture can be more simple for analysis and you can describe what kind of mirror nuclei and objects can be formed in your world
My course of the 2 semester will be Open, so it will be possible to attend it, but its aim is also to give some practice in writing scientific texts and make presentations in English, what you lose
With the best regards

Добрый день, Максим Юрьевич! С наступившим!
Высылаю вам третью версию реферата. Жду ваших поправок.
С уважением, Екатерина.

[Maxim Khlopov]

Dear Ekaterina,
My comments are in the attached file.
To make your life easier, I’d like to propose you to say at some place that your analysis is more definite, if you neglect effects of the 2d and 3d families and restrict your consideration by only the 1st family. In that case you should consider the forms of objects that can be formed in your mirror world.
With the best regards
