The discrete family symmetry as a possible solution to the flavour problem

In order to explain the fermions masses and mixing parameters appearing in the lepton sector of the Standard Model, one proposes the extension of its symmetry. A discrete, non-abelian subgroup of \(U(3)\) is added to the gauge group \(SU(3)_{C}\times SU(2)_{L}\times U(1)_{Y}\) . Apart from that, one...

Description
Summary:In order to explain the fermions masses and mixing parameters appearing in the lepton sector of the Standard Model, one proposes the extension of its symmetry. A discrete, non-abelian subgroup of \(U(3)\) is added to the gauge group \(SU(3)_{C}\times SU(2)_{L}\times U(1)_{Y}\) . Apart from that, one assumes the existence of one extra Higgs doublet. This article focuses mainly on the mathematical theorems and computational techniques which brought us to the results.
