“…Yet another application of these ideas is to the neutrino spectrum, and the formation of neutrino condensates; Hill, Luty and Paschos have considered the dynamical formation of right-handed neutrino Majorana condensates and the see-saw mechanism, [284] [284] (see also: [288]). Some of these models include additional exotic matter such as a sequential fourth generation or leptoquark bound states [401].…”
