RE: Getting grips on the pre-big-bang era with a universe/anti-universe pair
Hey @lemouth, nice read as always!
It has been found that right-handed neutrinos can be very good dark matter candidates as they are stable, super heavy (200 billion times heavier than the heaviest known particle) and super-weakly interacting.
So does that mean that right-handed neutrinos are not electromagnetically interacting? If so, how are their properties measured?
This has nothing to do with how neutrinos are writing, but how their spin is aligned or anti-aligned with their momentum.
Lmao!
No they don't. They are actually totally inert with respect to the Standard Model interactions. The only way to get to them in this model is through gravity. In other theories featuring right-handed neutrinos, there are usually other fundamental interactions in the game that could help as well).
I hope this clarifies :)
