Referat and Exam of Nikita Kantyshev
Posted: Mon 26 Apr 2010 17:06Тема "4 поколения фермионов"
Dear Nikita,
Thank you for approach to referat.
1. You should mention, what you know from our course about 4th family in our world - about 4th neutrino, stable 4th U-quark, composite dark matter.
So, please, correct the statement
Для начала взглянем как повлияет наличие четвертого отцепившегося в момент закалки нейтрино на интересующие нас величины в реальном мире.
In our world light fourth neutrino is experimentally excluded.
Then you can specify what kind of 4th generation you have in shadow world - sequential with 4 light neutrinos and mixing between all the 4 families, or 4th generation is separated from 3 lighter families.
Taking into account the set of ordinary particles please estimate the "chemical composition" of your mirror matter (for the case of sequential four shadow generations)
Regards
M.Yu.Khlopov
