The direct detection of relic neutrinos from the Big Bang was proposed in a paper by Steven Weinberg in 1962 [Phys. Rev. 128:3 (1962) 1457]. The signal for relic neutrino capture on tritium is the observation of electron kinetic energies emitted from a tritium target that are above the β-decay endpoint. The requirements on the experimental energy resolution for relic neutrino identification are constrained by the thermal model for neutrino decoupling in the early universe that predicts a… CONTINUE READING
