On the Cover

Isocontours of the neutrino vacuum appearance probability as a function of the three-neutrino CP phase δ_CP (abscissa) and a new "seesaw" phase φ deriving from nonunitarity (ordinate). Black lines correspond to the standard value δ_CP = 3π/2; blue (red) domain corresponds to a 10% (20%) deviation. Range is from zero to 2π for both axes.
