... First I will give a brief introduction on neutrino oscillation, and summarize the results in favor of neutrino oscillation (atmospheric neutrinos, solarneutrinos and KamLAND (and possibly LSND)). ...
... First I will briefly summarize the results of observation of atmospheric neutrinos and solarneutrinos and then I will explain the status of three and four flavor mixing schemes. ...
... 6) Supernova 1987a neturino time of flight studies as well as the SolarNeutrino experiment are consistent with the neutrino having a mass, but a very small mass, not one that can cosmologically dominate. ...
... the interaction scale of the neutrinos and now the neutrinos "free-stream" away from ... the neutrinos are not around to participate in this reheating and so the neutrino ... Therefore (T neutrino R)after = (T neutrino R)before = (TR)before. ...
... For M nu ~ 30 eV this is ~ 10 16 Solar Masses, which is an order of magnitude larger than the mass of a large cluster of ... For a neutrino dominated Universe, potentials of this mass would be the first to form. ...
