Abstract

In a two flavour world, the usual equal p, equal E, or equal v assumptions used to derive the neutrino oscillation length can be replaced by a specific definition of the velocity of the oscillating state which, unlike those assumptions, is compatible with exact production kinematics. This definition is further vindicated by the analysis of π_μ2 decay at rest.
