Web6 nov. 2011 · Lepton number is conserved because the electron has lepton number of +1 and a neutrino has lepton number of +1. In the case of a Z boson decaying into leptons one of them can be an electron (lepton number:+1) and the positron (lepton number:-1). It is as if this quantity does stuff because it conserves certain types of particles. WebThis means after each U-235 fission, the fission fragments must undergo on average 6 negative beta decays (6 neutrons must decay to 6 protons), and therefore 6 antineutrinos must be produced per each fission. ...

WebIn beta decay, a neutron-rich nuclide decays by the conversion of a neutron into a proton and an electron accompanied by the emission of an antineutrino. The antineutrino is an antiparticle (same mass but opposite electric charge and magnetic moment) of the neutrino. It is a lepton like an electron which is an elementary particle of spin ½.
