Добрый вечер! Темой реферата я выбрала: Теневой мир с 2 поколениями фермионов (Shadow matter with 2 generations of fermions).

С уважением, Людмила.

Доброго дня!
Это начало реферата. К сожалению, мне пока не очень понятно, как посчитать долю первичного гелия: для этого нам необходимо знать значение барион-фотонного соотношения => необходимо рассчитать концентрации фотонов и барионов с учетом зеркальных частиц. Верно ли это?
С уважением, Людмила.

Dear Liudmila,
Thank you for draft, though, of course, there is a lot of work left.
The properties of your mirror matter are determined by your physics, in particular, whether you have the second generation stable, or not. To pretend on excellent result, you should consider the influence of ordinary particles on the mirror matter and vice versa and come to conclusions about possible forms of mirror matter.
Baryon/photon ratio in ordinary and mirror matter is determined by baryosynthesis, which you either deduce from your model, or make assumptions, which correspond to the observed properties of the ordinary matter.
You should also mention, whether, you have mechanisms for inflation in your scenario

Добрый вечер!
Это вторая версия реферата: оценена доля первичного гелия. Надо ли рассматривать возможность того, чт часть нейтронов распалась к моменту образования гелия?
С уважением. Людмила.
P.S.
С наступившим новым годом!

Dear Liudmila,
Happy new year to you too!
You should divide your text on chapters, describing your physical model, your cosmological scenario and the properties of your dark matter objects that follow from the cosmological evolution of your shadow matter.

Dear Liudmila,

Dear Liudmila,
Of course, it will facilitate our work on your referat in future. But you should present your referat in the 2 semester in English (I'll give my course in English), but the essential points of your topic should be put in the Russian text.
