Fermion Masses and Flavor Mixing in A Supersymmetric SO(10) Model
we study fermion masses and flavor mixing in a supersymmetric SO(10) model, where 10, 120 and 126 Higgs multiplets have Yukawa couplings with matter multiplets and give masses to quarks and leptons through the breaking chain of a Pati-Salam group. This brings about that, at the GUT energy scale, the lepton mass matrices are related to the quark ones via several breaking parameters, and the smal...
متن کاملSupersymmetric theory of flavor with radiative fermion masses.
Supersymmetric theories involving a spontaneously broken avor symmetry can lead to fermion masses which vanish at tree level but are generated by radiative corrections. In the context of supersymmetric theories with minimal low energy eld content we discuss which fermion masses and mixings may be obtained radiatively, and nd that constraints from avor changing phenomenology imply that only the ...
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 کاملLepton Flavor Violation and Fermion Masses
Lepton flavor violation may be a signature of “GUT scale” physics, if the messenger scale for SUSY breaking is above the “GUT scale.” We elaborate on the details of this simple statement in the following talk.
متن کاملFermion 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 ...
