Title: Composite flavon-Higgs models

Abstract

We consider a composite Higgs model based on theU(6)/Sp(6) coset, where an U(1) subgroup of Sp(6) is identified as the flavor symmetry. A complex scalar field s, which is a pseudo-Nambu-Goldstone boson of the broken symmetry, carries a flavor charge and plays the role of a flavon field. The U(1)F flavor symmetry is then broken by a VEV of the flavon field, which leads to a small parameter and generates the mass hierarchy between the top and bottom quarks. A light flavon below the TeV scale can be naturally introduced, which provides a fully testable model for the origin of flavor hierarchy. A light flavon also leads to substantial flavor changing neutral currents, which are strongly constrained by the flavor experiments. The direct search of additional scalar bosons can also be conducted in HL-LHC and future hadron colliders.

Flavorful composite Higgs model: Connecting the $B$ anomalies with the hierarchy problem

Journal Article Chung, Yi - Physical Review D

We present a model which connects the neutral current B anomalies with composite Higgs models. The model is based on the minimal fundamental composite Higgs model with SU(4)/Sp(4) coset. The strong dynamics spontaneously break the symmetry and introduce five Nambu-Goldstone bosons. Four of them become the Standard Model Higgs doublet, and the last one, corresponding to the broken local U(1)' symmetry, is eaten by the gauge boson. This leads to an additional TeV-scale Z' boson, which can explain the recent B anomalies. The experimental constraints and allowed parameter space are discussed in detail.

Phenomenology of flavor-mediated supersymmetry breaking

Journal Article Kaplan, D Elazzar ; Kribs, Graham D - Physical Review. D, Particles Fields

The phenomenology of a new economical supersymmetric model that utilizes dynamical supersymmetry breaking and gauge mediation for the generation of the sparticle spectrum and the hierarchy of fermion masses is discussed. Similarities between the communication of supersymmetry breaking through a messenger sector and the generation of flavor using the Froggatt-Nielsen (FN) mechanism are exploited, leading to the identification of vector-like messenger fields with FN fields and the messenger U(1) as a flavor symmetry. An immediate consequence is that the first and second generation scalars acquire flavor-dependent masses, but do not violate flavor changing neutral current bounds since their mass scale,more »« less

Fermion Mass Hierarchy and New Physics at the TeV Scale

Journal Article Nandi, S - AIP Conference Proceedings

In this talk, I present a new framework to understand the long-standing fermion mass hierarchy puzzle. We extend the Standard Model gauge symmetry by an extra local U(1){sub S} symmetry, broken spontaneously at the electroweak scale. All the SM particles are singlet with respect to this U(1){sub S}. We also introduce additional flavor symmetries, U(1){sub F}'s, with flavon scalars F{sub i}, as well as vectorlike quarks and leptons at the TeV scale. The flavon scalars have VEV in the TeV scale. Only the top quark has the usual dimension four Yukawa coupling. EW symmetry breaking to all other quarks andmore »« less

A more natural composite Higgs model

Journal Article Cheng, Hsin-Chia ; Chung, Yi - Journal of High Energy Physics (Online)

Composite Higgs models provide an attractive solution to the hierarchy problem. However, many realistic models suffer from tuning problems in the Higgs potential. There are often large contributions from the UV dynamics of the composite resonances to the Higgs potential, and tuning between the quadratic term and the quartic term is required to separate the electroweak breaking scale and the compositeness scale. We consider a composite Higgs model based on the SU(6)/Sp(6) coset, where an enhanced symmetry on the fermion resonances can minimize the Higgs quadratic term. Moreover, a Higgs quartic term from the collective symmetry breaking of the littlemore »« less

The unnatural composite Higgs

Journal Article Barnard, James ; Gherghetta, Tony ; Ray, Tirtha Sankar ; ... - Journal of High Energy Physics (Online)

Composite Higgs models can trivially satisfy precision-electroweak and flavour constraints by simply having a large spontaneous symmetry breaking scale, f ≳ 10 TeV. This produces a ‘split’ spectrum, where the strong sector resonances have masses greater than 10 TeV and are separated from the pseudo Nambu-Goldstone bosons, which remain near the electroweak scale. Even though a tuning of order 10^–4 is required to obtain the observed Higgs boson mass, the big hierarchy problem remains mostly solved. Intriguingly, models with a fully-composite right-handed top quark also exhibit improved gauge coupling unification. By restricting ourselves to models which preserve these features wemore »« less
