โœฆ Synopsis

Measurements of the Gottfried Sum Rule suggest significant violation of flavor symmetry in the proton sea. This has recently been confirmed in measurements of pp and pD Drell-Yan processes by the E866 experiment. We review the question of flavor symmetry violation, and possible theoretical explanations of this effect. The interpretation of large flavor symmetry violation rests on the assumption of parton charge symmetry. Our model calculations suggest charge symmetry violation [CSV] for parton valence distributions of a few percent. We review present experimental limits on CSV, and we suggest new experiments which might detect parton CSV.

A group theoretical framework is proposed for a detailed characterization of the shapes of electronic charge distributions of general, asymmetric molecules. The proposed shape groups are the homology and cohomology groups of charge density contour surfaces. These shape groups depend on two real para
