[EX Q]: The reciprocal relationship between the eigenvalues of the mass matrix of these particles is called the "seesaw mechanism"; the larger eigenvalue may be the mass of their "sterile" variety. One phenomenon predicted by Pontecorvo involving these entities was searched for by (*) MINOS. Reines and Cowan used an aqueous cadmium chloride solution to detect them, and other detectors tend to include large volumes of material, such as Super Kamiokande. For 10 points, name these leptons, the nearly massless products of radioactive decay whose varieties include the muon and tau and which are represented by the letter nu.

[EX Q]: Japan's Chikyu Hakken is trying to reach this region, and n-waves travel along its upper boundary. Post-perovskite forms in the bottommost part of this region, the D double prime layer. P-waves slow down and S-waves disappear past the bottom of this region, and its top features a P-wave velocity jump from approximately seven to approximately eight kilometers per second. The low velocity zone of the asthenosphere is found in the upper part of this region. It is sandwiched between the Gutenburg discontinuity and the Moho, and this layer's namesake plumes form hotspots. For 10 points, name this layer of the earth between the crust and the core.
