The Dualized Standard Model (DSM) is an attempt to answer some of the questions left open by the Standard Model, such as the reason for the existence of 3 fermion generations and of Higgs fields, and to explain the observed values of some of the Standard Model’s .

The fermion mass hierarchy and mixing patterns are also explained. Quarks and leptons are seen to have very different mixing patterns in agreement with experiment. The model offers a perturbative method for calculating mixing parameters and mass ratios between generations, allowing us to calculate to 1-loop order all the 9 CKM matrix elements.   The special feature of this model crucial for deriving the above results is a fermion mass matrix which changes its orientation (rotates) in generation space with changing energy scale, a feature which is shown to have direct empirical support. Based on a non-Abelian generalization of electric–magnetic duality, the Dualized Standard Model (DSM) suggests a natural explanation for exactly three generations of fermions as the "dual colour" symmetry broken in a particular manner. The resulting scheme then offers on the one hand a fermion mass hierarchy and a perturbative method for calculating the mass and mixing parameters of the. A first look at the fermion masses.

The Dualized Standard Model has scored a number of successes in explaining the fermion mass hierarchy and mixing pattern. This note contains updates to those results including (a) an improved treat-ment of neutrino oscillation free from previous assumptions on neu-trino masses, and hence admitting now the preferred LMA solution to. A Dualized Standard Model recently proposed affords a natural explanation for the existence of Higgs fields and of exactly 3 generations of fermions, while giving at the same time the observed fermion mass hierarchy together with a tree-level CKM matrix equal to the identity matrix.   Abstract: The Dualized Standard Model offers a natural place both to Higgs fields and to fermion generations with Higgs fields appearing as frame vectors in internal symmetry space and generation appearing as dual colour. If they are assigned those niches, it follows that there are exactly 3 generations of fermions, and that at the tree-level, only one generation has a mass (fermion mass hierarchy) while the CKM matrix . scheme, which we call the Dualized Standard Model (DSM), explains the fermion mass hierarchy and the mixing phenomena and suggests even a per-turbative method for calculating mass and mixing parameters. Calculations with it have been carried out so far to .
