As for neutrinos, there seems to be some argument about what they are. Wallace Thornhill hypothesizes that they are subatomic structures of vanishingly small mass. When energy is imparted into them, they then become other atomic particles with which we are more familiar.
Hope that helps a bit.
Why neutrinos don't exist
The neutrino supposition is based on a nonexistent "need" to balance a situation that didn't need balancing! An earlier case of trying to fit relativity into physics. Ham-handed at that.
Hope that helps a bit more.
