Source sentences:
text: In theory, it is impossible for Lepton number to be exactly conserved, because unlike electric charge, it does not come with an electric field associated to it.
text: The lepton number is just a conserved quantity in all observed processes, with the almost certain exception of neutrino oscillations.
text: (Note: The total lepton number is, as far as we know, conserved in nature.
text: Therefore, muon-lepton number is conserved.
text: Thus, the muon-lepton number is conserved.
text: However, theory does not necessitate that lepton number always be conserved.
text: Scientists consider the total lepton number to be conserved if the summed family lepton flavor numbers before a reaction remain unchanged after a reaction.
text: Likewise, when a W− boson decays into an electron and an antineutrino, lepton number is conserved because the W− boson is a non-lepton, the electron is a lepton, and the antineutrino is an antilepton.
text: As far as we know, baryon number and lepton number are absolutely conserved, which means that baryons and leptons can only be created or destroyed in particle-antiparticle pairs.21.1 Antiparticles are represented by the symbol of the particle with an overbar.
text: (Note: The total lepton number is, as far as we know, conserved in nature.
text: Thus, the muon-lepton number is conserved.
text: Electron-lepton number is also conserved, as for , whereas the net electron-lepton number of the decay products is .
