Quarks, Squarks and Textures
Abstract
By studying symmetric mass textures for the up and down quark sectors, and expanding in a small parameter λ sinθC, bounds are set on entries commonly assumed to vanish. Consequences of a 2 + 1 family structure which can result from horizontal symmetry are examined. Generalizing to squarks, we study suppression of Flavor Changing Neutral Currents by mass degeneracy and/or small mixing angles.
