Mirror world with G’F=2*GF.

Вы правильно стали говорить о количестве первичного гелия-4. Хорошо, если бы вы представили сами численные выкладки, которые приводят к предсказанию количества гелия-4. Обратите внимание также на распад нейтрона в отношении к данному предсказанию.
Всего хорошего

Здравствуйте
В оценке количества первичного гелия-4 обратите внимание также на зависимость времени жизни нейтрона от GF.
Также интересно, если бы вы довели вами уместно поднятый вопрос об изменении ограничения на число сортов нейтрино до вывода о том, можно ли компенсировать (с т.зр. количества гелия-4) изменение GF->2GF изменением числа сортов нейтрино?

Dear Ivan,
In addition to comments by Konstantin Mikhailovich please take into account that you have
-ordinary particles with all known interactions of the standard model
- and in addition the set of mirror particles (the same content as ordinary particles) with same group of symmetry SU(3)xSU(2)xU(1) with the only difference in the value of Fermi constant in mirror weak interaction.
You should first consider evolution of mirror matter (in the presence of ordinary matter) and then to analyze the influence of this mirror matter on ordinary matter.
I also would like to recommend you to make your referat in a proper form: there should be Introduction, Sections and Conclusion.
There should be a list of references in the end.

третий вариант с некоторыми добавлениями

Dear Ivan,
I have to repeat that Referat should contain Introduction, description of physical model with emphasis on cosmologically important consequences, analysis of these consequences and Conclusion.
The list of references should exceed 3.
Please make proper formulation of your problem in Introduction.
The Section "Fizichzskaya model" must contain description of your physical model.
Then you specify cosmologically important consequences of model
Then you should present as a special Section Cosmological scenario.
Please take into account that you have
-all the ordinary particles with all known interactions of the standard model
- and in addition the set of mirror particles (the same content as ordinary particles) with same group of symmetry SU(3)xSU(2)xU(1) with the only difference in the Fermi constant of mirror weak interaction.
It means that you should discuss as cosmologically important consequences the existence of the whole set of mirror particles.
You should first consider evolution of mirror matter (in the presence of ordinary matter) and then to analyze the influence of this mirror matter on ordinary matter.
I think that now we can skip the second part of your task - constraints on change of Fermi constant for ordinary particles from nucleosynthesis. Please concnetrate only on scenarion with mirror world with a 2 times larger Fermi constant.
In Conclusion you should briefly mention if there are mechanisms of inflation or baryosynthesis in your model.

Здравствуйте
вы упомянули об уменьшении времени жизни нейтрона, но не учли это в оценке количества первичного гелия.
Всего хорошего
