Referat and Exam of Denis Kasatkin

[Maxim Khlopov]

Dear Denis,
My comments are in the attached file.
You should stipulate all the stable particles in your model.
You should specify, whether you consider baryon asymmetrical or baryon symmetrical case and then calculate the frozen out amounts of your stable species

Здравствуйте! Я рассматриваю зарядово-симметричный мир. Я посчитал концентрации стабильных частиц.

Здравствуйте! Отправляю исправленный вариант реферата.

Dear Denis,
I didn't go in details in the attached file with my comments, since there is the principal point, which you should address and correct. In the world without weak interactions you don't have Higgs mechanism, therefore all your fermions are massless (at the bare mass level). Hadrons acquire mass due to confinement and you should find the scale of confinement for your case, taking into account the number of mirror quarks.
With the best regards

Добрый вечер. Я дополнил реферат.

[Maxim Khlopov]

Dear Denis,
Thank you. However, there is still needed correction on the QCD scale in your case and in descritpion of freezing out of hadrons.
