  The scalar composite representations of the electroweak symmetry group of the
Standard Model are exhibited in the case of two generations of quarks. The link
between `strong' and `electroweak' eigenstates is investigated, showing that
the quark content commonly attributed to pseudoscalar mesons needs to be
modified. After doing so, the mechanism suppressing the decays K{+} into Pi{+}
Pi{0} with respect to K{short} into Pi{+} Pi{-} is unraveled, without reference
to any model of quark spectator or `factorization' hypothesis. The same
mechanism is shown to suppress the decays K{long} into two pions. Leptonic and
semi-leptonic decays are also studied. The mass relations between`electroweak'
eigenstates, verified at better than one percent, mass(Pi{3})/mass(Pi{+}) =
cos(theta Cabibbo) = mass(chi{1910})/mass(Ds) are obtained.
