Neutrino masses are generated through effective dimension-five Weinberg operators. Charged lepton mass hierarchies are generated with an ...

In combination with supersymmetry, flavor symmetry may relate quarks with leptons, even in the absence of a grand-unification group. We propose an SU(3)�SU(2)�U(1) model where both supersymmetry and the assumed A4 flavor symmetries are softly broken, reproducing well the observed fermion ...

We recently proposed a spontaneous A4 flavor symmetry breaking scheme implemented in a warped extra dimensional setup to explain the observed pattern of quark and lepton masses and mixings. The quark mixing is absent at leading order in the VEV expansion and it is induced at next-to-leading order by bulk ...

We discuss the phenomenology of doubly and singly charged Higgs bosons [of SU(2)L-triplet fields] in the simplest A4-symmetric version of the Higgs triplet model. Mass eigenstates of these Higgs bosons are obtained explicitly from the Higgs potential. It is shown that their decays into a pair of leptons have unique ...

We propose a supersymmetric A4�SU(5) model of quasidegenerate neutrinos which predicts the effective neutrino mass mee relevant for neutrinoless double beta decay to be proportional to the neutrino mass scale, thereby allowing its determination approximately independently of unknown Majorana phases. Such a natural quasidegeneracy is ...

The retention of flavor during freeze drying was studied with model systems. Mechanisms by which flavor retention phenomena is explained were developed and process conditions specified so that flavor retention is optimized. The literature is reviewed and ...

The standard model of electro-weak and strong interactions is a successful theory for particles and their interactions. Recent studies of solar, atmospheric and reactor neutrinos established that neutrinos have nonzero mass and they mix among themselves much like the quarks, thereby providing the first evidence of new physics beyond the standard model. The ...

The Zee model generates neutrino masses at the one-loop level by adding charged SU(2)L-singlet and extra SU(2)L-doublet scalars to the standard model of particle physics. We introduce the softly broken A4 symmetry to the Zee model as the origin of the nontrivial structure of the lepton ...

The authors review the equivalence of the two-flavor Skyrme-Witten model and the two-flavor large-N[sub c] quark model. The claimed equivalence for three flavors between these two models is shown to be incorrectly given in the literature, and the properly equivalent ...

We propose an A4 flavor-symmetric SU(3)?SU(2)?U(1) seesaw model where lepton number is broken spontaneously. A consistent two-zero texture pattern of neutrino masses and mixing emerges from the interplay of type-I and type-II seesaw contributions, with important phenomenological predictions. We show that, if the Majoron becomes massive, such seesaw ...

Flavor constraints in a bosonic technicolor model are considered. We illustrate different sources for their origin, and emphasize, in particular, the role played by the vector states present in the technicolor model. This feature is the essential difference in comparison to an analogous model with two fundamental ...

Can the Large Hadron Collider explain the masses and mixings of the known fermions? A promising possibility is that these masses and mixings are determined by flavor symmetries that also govern new particles that will appear at the LHC. We consider well-motivated examples in supersymmetry with both gravity and gauge mediation. Contrary to spreading belief, new physics need not ...

Grand unified models of the strong and electroweak forces generally predict some types of flavor unification.

Models of minimal lepton flavor violation where the seesaw scale is higher than the relevant flavor scale predict that all lepton flavor violation is proportional to the charged lepton Yukawa matrix. If extra vectorlike leptons are within the reach of the LHC, it will be possible to test the resulting predictions ...

The neutrino oscillation data are in very good agreement with the tribimaximal mixing pattern: sin?2?23=1/2, sin?2?12=1/3, and sin?2?13=0. Attempts to generate this pattern based on finite family symmetry groups typically assume that the family symmetry is broken into different subgroups in the charged-lepton and the neutrino mass matrices. This leads to a technical problem, where the cross ...

The key point is that extended scalar sectors will generically lead to flavor changing neutral currents, which are strongly constrained by experiments. Because of the large parameter space in the ...

Theories where the standard model fields reside on a 3-brane, with a low fundamental cutoff and extra dimensions, provide alternative solutions to the gauge hierarchy problem. However, generating flavor at the TeV scale while avoiding flavor-changing difficulties appears prohibitively difficult at first sight. We argue to the contrary ...

In {chi}QM, a quark can emit Goldstone bosons. The flavor symmetry breaking in the Goldstone boson emission process is used to interpret the nucleon flavor-spin structure. In this paper, we study the inner structure of constituent quarks implied in {chi}QM caused by the Goldstone boson emission process in nucleon. From a simplified ...

We present a class of supersymmetric models in which flavor symmetries are broken dynamically, by a set of composite flavon fields. The strong dynamics that is responsible for confinement in the flavor sector also drives flavor symmetry-breaking vacuum expectation values, as a consequence of a quantum-deformed ...

Many extensions of the standard model (SM) generate contributions to flavor changing neutral current (FCNC) processes that must have sufficient flavor suppression to be consistent with experiments, if the new physics (NP) is associated with a scale of a TeV.
