May 31, 2016 at 4:08 comment added Luboš Motl Do you think that "composite" and "bound" is something else here? Why?
May 30, 2016 at 15:12 comment added NUU Just an idée fixe, which I will probably discuss in another question. It's not really about 'bound' states...
May 30, 2016 at 14:57 comment added Luboš Motl There can't be a bound state of an electron and a neutrino because it would have to be lighter than the electron (neutrino is almost massless) to be bound, and it would replace electrons in the atoms etc. Also, there's no strong enough interaction to hold neutrino bound to pretty much to anything. Moreover, I don't understand why you would discuss bound states, they are calculable from the Standard Model, right?
May 30, 2016 at 14:25 comment added NUU Now THAT is pretty exotic! What I had in mind is rather some (yet to be fully specified) composite model of (gauge) bosons. If $W^+$ would be some composite of $e^+$ and $\nu$, there should also be composites of $e^+$ and $e^+$ and so on...
