Abstract

We derive the relation between the amplitudes of short-baseline appearance and disappearance oscillations in 3 + N-s neutrino mixing schemes which is the origin of the appearance-disappearance tension that is found from the analysis of the existing data in any 3 + N-s neutrino mixing scheme. We illustrate the power of the relation to reveal the appearance-disappearance tension in the cases of 3 + 1 and 3 + 2 mixing using the results of global fits of short-baseline neutrino oscillation data.
