N2 - We show in detail the general relationship between the Schrödinger equation approach to calculating the MSW effect and the quantum field-theoretical S-matrix approach. We show the precise form a generic neutrino propagator must have to allow a physically meaningful “oscillation probability” to be decoupled from neutrino production fluxes and detection cross sections, and explicitly list the conditions—not realized in cases of current experimental interest—in which the field theory approach would be useful.
