Query: Phenomenology from relativistic Levy-Schroedinger equations: Application
  to neutrinos   In continuation of a previous paper a close connection between Feynman
propagators and a particular L\'evy stochastic process is established. The
approach can be easily applied to the Standard Model SU_C(3)xSU_L(2)xU(1)
providing qualitative interesting results. Quantitative results, compatible
with experimental data, are obtained in the case of neutrinos.
