About Composite Scalar Representations of the Electroweak Symmetry Group of the Standard Model
Abstract
Description
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.
