Fermion Masses and Mixing in Thick Branes
Fermion masses and mixing, both in the quark and leptonic sector, are discussed within the approach to the Yukawa puzzle proposed by Arkani-Hamed and Schmaltz. In the quark sector we have shown that at least two extra dimensions are necessary in order to obtain sufficient CP violation, while reproducing the correct quark mass spectrum and mixing angles. We have also studied the consequences of ...
متن کاملFermion Masses and Mixing in Four and More Dimensions
We give an overview of recent progress in the study of fermion mass and flavor mixing phenomena. Mass matrix ansatze are considered within the SM and SUSY GUTs where some predictive frameworks based on SU(5) and SO(10) are reviewed. We describe a variety of schemes to construct quark mass matrices in extra dimensions focusing on four major classes: models with the SM residing on 3-brane, models...
متن کاملFermion Masses and Mixing in Intersecting Branes Scenarios
We study the structure of Yukawa couplings in intersecting D6-branes wrapping a fac-torizable 6-torus compact space T 6. Models with MSSM-like spectrum are analyzed and found to fail in predicting the quark mass spectrum because of the way in which the family structure for the left-handed, right-handed quarks and, eventually, the Higgses is 'factorized' among the different tori. In order to cir...
متن کاملFermion masses, mixing angles, and supersymmetric SO(10) unification.
We reanalyse the problem of fermion masses in supersymmetric SO(10) grand unified models. In the minimal model, both low energy Higgs doublets belong to the same 10 representation of SO(10) implying the unification not only of the gauge but also of the third generation Yukawa couplings. These models predict large values of tanβ ∼ 50. In this paper we study the effects of departing from the mini...
متن کاملFermion Masses and Bi-large Lepton Mixing from Singular Matrices
We discuss conditions under which bi-large mixing in the lepton sector is achieved assuming that all Yukawa matrices and the right-handed neutrino mass matrix have the same singular form in the leading order. Due to obvious quark lepton symmetry, this approach can be embedded into grand unified theories. The right-handed neutrino mass scale can be identified with the GUT scale and, as a consequ...
