Warm Dark Matter candidates: neutrinos, axions, extra relativistic species currently unknown. Cold Dark Matter candidates: many. Pick one (or many!): Z primes, the lightest supersymmetric particle (LSP), gravitino, gaugino, neutralino, ELKO fields, Majorana spinors, the infinite component Majorana field, unparticles, … Continue reading
There are some indirect constraints/bounds on neutrino masses provided by Cosmology. The most important is the one coming from the demand that the energy density of the neutrinos should not be too high, otherwise the Universe would collapse and it … Continue reading
This new post ignites a new thread. Subject: the Science of Neutrinos. Something I usually call Neutrinology. I am sure you will enjoy it, since I will keep it elementary (even if I discuss some more advanced topics at some … Continue reading
