Flavour structure , flavour symmetry and supersymmetry ∗
One of the most obscure sides of particle physics concerns the fermion flavor structure. This is a complex problem with different aspects questioning the origin of the mass spectrum and mixing pattern of quarks and leptons (including neutrinos) and CP-violation, as well as the suppression of flavor changing (FC) neutral currents, the strong CP-problem, etc. [1]. Presently, thanks to the new dat...
متن کاملSequential Flavour Symmetry Breaking
The gauge sector of the Standard Model (SM) exhibits a flavour symmetry which allows for independent unitary transformations of the fermion multiplets. In the SM the flavour symmetry is broken by the Yukawa couplings to the Higgs boson, and the resulting fermion masses and mixing angles show a pronounced hierarchy. In this work we connect the observed hierarchy to a sequence of intermediate eff...
متن کاملNeutrino Masses and Flavour Symmetry
The problem of neutrino masses and mixing angles is analysed in a class of supersymmetric grand unified models, with SO(10) gauge symmetry and global U(2) flavour symmetry. Adopting the seesaw mechanism for the generation of the neutrino masses, one obtains a mass matrix for the left–handed neutrinos which is directly related to the parameters of the charged sector, while the unknown parameters...
متن کاملDiscrete Lorentz symmetry and discrete time translational symmetry
The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are themanifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.We argue that, following the space translational symmetry, the continuous Lorentz symmetry should also be broken into a discrete one, which further implies that the con...
