An anti electron neutrino is a 'lepton' with a lepton number of -1 (because its anti lepton)
It has no charge
It has no baryon number (its not a baryon, only baryons and anti baryons have baryon numbers)
It is there to conserve energy, as experiments showed there was excess energy given off, and scientist concluded the idea of neutrinos. Neutrinos conserve energy in particle interactions
Ik this is probably easy but like why does a b- decay go to proton + electron + anti electron neutrino. WHAT?? what is an anti electron neutriono? like charge, lepton number thanks
