That's a fascinating new theory. Thanks for breaking it down so that even I could follow - I didn't feel the need to call the committee for the prevention of torture. ;-)
You say the right-handed neutrino would be almost impossible to detect - is this because of its weak interactions with other particles?
Thanks for the nice comment.
I was also shocked when I typed CPT in google to find a few references.... (but this is not the stupidity in this post). And then I laughed... ;)
It is in fact completely decoupled and we can only track its gravitational effects to see it. Which is why no dark matter experiment will ever be able to see it...
