Query: Neutrino Physics and the Mirror World   Improper Lorentz Transformations can be retained as exact symmetries of
Nature if the particle content and gauge group of the Standard Model are
doubled. The resulting ``Exact Parity Model (EPM)'' sees each ordinary particle
paired with a mirror analogue. If neutrinos have mass and if they mix, then the
EPM predicts that each ordinary neutrino will be maximally mixed with its
mirror neutrino partner. This provides a very simple explanation for the very
large mixing angle observed for atmospheric muon neutrinos by SuperKamiokande
and other experiments. Maximal mixing for electron neutrinos is also well
motivated by the solar neutrino problem. If small interfamily mixing is
switched on, then the LSND anomaly can also be accomodated by the EPM. The EPM
thus provides a unified, simple and to some extent predictive framework for
explaining all of the anomalous neutrino data. This talk will briefly review
the EPM or mirror neutrino scenario.
