Abstract

We present a search for differences in the oscillations of antineutrinos and neutrinos in the Super-Kamiokande-I, -II, and -III atmospheric neutrino sample. Under a two-flavor disappearance model with separate mixing parameters between neutrinos and antineutrinos, we find no evidence for a difference in oscillation parameters. Best-fit antineutrino mixing is found to be at (Δm ^̄2,sin ²2θ̄)=(2.0×10 ^-3eV ²,1.0) and is consistent with the overall Super-K measurement.
