Dear Oleg,
It gives you "3" as an intermediate control mark.
If you want more, you should offer a first draft before the deadline tomorrow

Dear Oleg,
I highly estimate your Bibliography and the use of works, going far beyond the material of my course.
My comments are in the attached file.
You should more extensively study the role of all the possible forms of stable particles, predicted in your model.
Regards

Dear Oleg,
In the absence of Higgs mechanism masses of leptons and bare masses of quarks are zero, so that hadrons have same masses, determined by QCD confinement, which they acquire only after QCD phase transition.
It can strongly influence your scenario.

Здравствуйте, Максим Юрьевич!
Я предполагал, что частицы имеют массу, просто она генерируется не механизмом Хиггса, а вводится руками. Насколько я понимаю, для группы SU(3)*U(1) это возможно. Правильно ли это?

Dear Oleg,
The case of massless fermions seems more natural in the absence of Higgs mechanism.
There is an interesting question, whether charged leptons are massless, or they get some mass due to their electromgnetic interaction. However, in principle, you can go beyond the physics of your model and assume some additional mechanism of mass generation. Then you can retain your results, but you have a set of various stable particles.

Dear Oleg,
For the ratio of decay rates of inflaton to ordinary and mirror particles, the contribution of mirror particles in the total density after reheating is negligible in your scenario.
You didn't stady effects of diquark and tripple states of heavy quarks, like ttt, tt and their antiparticles.
The work on the further improvement of the text depends on your plans for the 2 semester - do you plan to attend my course or not?
My comments are in the attached file
