This composition generates a new hypercharge and a new kind of color called supercolor. Such quark composition explains the Kobaiashi-Maskawa matrix elements in terms of selection rules based on the new hypercharge. Also it is shown that the doublet of quarks top/bottom is quite similar to the doublet charm/strange. Besides, it is also shown that there should exist three Higgs bosons involved in the generation of quark masses.14 pages, LatexHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentHigh Energy Physics - Theorytext
