[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]: depicted a basket of fruit level with a small raised chest and an urn in a painting that portrays a hunched writing man next to Mary and Jesus. He painted an amphora resting atop a column in the background of a scene in which an angel hustles the holy family down a road.

[EX Q]: was discovered in 1986 by Roger Davies, Alan Dressler and five other scientists collectively known as The Seven Samurai. Its discovery was made clear due to peculiarities in the Tully-Fischer relationship of up to 700 kilometers-per-second and is associated with a filament-like red-shift that is directed back at the observer; a pattern called the Fingers of God. Some astronomers believe that it is a supercluster with its center at Abell 3627, but since it lies within the Zone of Avoidance in the direction of the Hydra and Centaurus constellations, studies made to research this object in the visible spectrum have been made difficult. This structure is located just in front of a 500 million light year long filament of both baryonic and dark matter called the Great Centaurus Wall. Recently estimated to be 250 million light years across, FTP, identify this gravitational anomaly that is named from its tendency to draw galaxies toward it.
