| dc.description | Neutrino physics is used as an illustrative example for an elementary introduction to the computational method of Feynman loop-diagrams and decay rates. If the neutrinos are as massive as recently reported by the Super-Kamiokande results, the heaviest neutrino $ν_H$ would not be stable. Although chargeless, it could decay -- by quantum loop effect -- into a lighter neutrino $ ν_L$ by emitting a photon: $ν_H \to ν_L + γ$. If kinematically possible, the $ν_H \to ν_L$ + e$^+$ + e$^-$ mode could occur at the tree diagram level and furthermore get enhanced, at one-loop radiative corrections, by a large logarithm of the electron mass acting as an infrared cutoff. | |
