[Leonova Tanya MEPhI]

Maxim Yurievich,

You will find my work in the attachment. Its subject is "Shadow matter with 1 generation of fermions".

BR,
Tanya Leonova

Dear Tatiana,
Thank you for draft.
Your statements should be directly linked to the physics of your model.
Some comments are in the attached file
With the best regards

Good evening!
Thank you for your comments. This is my second referat version, but I am not sure that I have corrected all the mistakes.
BR,
Tanya Leonova

[Maxim Khlopov]

Dear Tatiana,
My comments are in the attached file.
The sentences and phrases, in which Grammar of stylistic corrections are needed, are underlined.
Please add discussion of shadow objects, predicted in your model (most probably you'll have large He/p ratio in your shadow matter, what should influence the structure and evolution of your shadow stars).
With the best regards
M.Yu.Khlopov

Good evening!
Thank you for your answers and comments. This is my next referat version.

Dear Tatiana,
My small comments are in the attached file.
The main point is that there is no clear and qualitative account for the difference
of temperatures in mirror and ordinary worlds in the calculation of the primordial He abundance.

Maxim Yurievich,
What do you mean by saying: "there is no clear and qualitative account for the difference
of temperatures in mirror and ordinary worlds in the calculation of the primordial He abundance." I calculated the ratio between freeze out temperatures in the ordinary world and in the shadow world. Is this ratio constant during all stages of evolution?
BR,
Tanya Leonova

[Maxim Khlopov]

Dear Tatiana,
You assume the difference of temperatures in mirror and ordinary plasma, therefore the corresponding ratio of temperatures, which doesn't change in the adiabatic expansion, should be manifestly present in the calculations of k_o and k_s.
With the best regards
M.Yu.Khlopov
