■概要
Primordial neutrinos from the Big Bang are about 100 times more numerous than solar neutrinos, and at least two-thirds of them are now non-relativistic. These relic neutrinos, which have never been detected, decoupled in the early universe, with definite helicity (neutrinos left-handed and antineutrinos right handed). However, their subsequent propagation through gravitational inhomogeneities and even background gravitational radiation, as well as cosmic and galactic magnetic fields partially flips their helicities, and can produce noticeable effects in their eventual detection. I will briefly discuss future detection of relic neutrinos.
