Main Question or Discussion Point
I can't seem to find the mass of an anti electron neutrino in MeV. I found that in beta radiation one down quark breaks into an up quark, an electron, and an anti electron neutrino. The mass in MeV of a down quark is 4.8, the mass of an up quark is 2.4 MeV, the mass in MeV of an electron is 0.511 MeV. So the mass of an anti electron neutrino should be 1.889 MeV. However I can't find a place to make sure I am right. Thank you and forgive me if i'm wrong.
