Three-flavour neutrino-mixing implications of the LSND result

The LSND result is shown to fit into a minimal three-flavour neutrino-mixing scenario capable of describing all known experimental facts provided the large ΔM2=m32−m22∼m32−m12 lies in the range 2.5×10−1<ΔM2<3.0 eV2. In this range the value of Pμτ is expected to be about 5% or larger.
