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.

After this artist challenged an attributed painting to Correggio that was actually by Francesco Furini, he was inspired to paint Sigismunda. His portrait of Captain Coram was painted for the Foundling Hospital its subject founded. This artist's painting Night depicts a magistrate who has the contents of a chamber pot emptied over him.

For 10 points, name this satirist who depicted seedy London life in A Harlot's Progress and A Rake's Progress.

Porath and Flodin introduced dextran-based gels for the size-exclusion variety of this process, and this process's optimal velocity can be found with the Van Deemter equation. The analyte is polar and the column non-polar in the reverse-phase version of the(*) high-performance liquid type of this process. The retention time is calculated as the sample distance divided by the solvent-front distance in the thin-layer and paper versions of this process. For 10 points, identify this technique that passes a mobile phase through a stationary phase to separate constituents of a mixture.
