Mass of NeutrinoMass of Neutrino
Do we need to measure the neutrino mass since the antineutrino mass limit is known
Sergey Eliseev SFB-Meeting 9072009
Yes bull to confirm the results taken from tritium measurements
(with completely different systematic uncertainties)
bull hopefully can be useful for a check of CPT-conservation for neutrinos
