Top and Bottom Seesaw from Supersymmetric Strong Dynamics

TL;DR

This paper introduces a supersymmetric strong dynamics-based top and bottom seesaw model where composite quarks and gauge bosons emerge from Seiberg duality, leading to a Higgs sector compatible with the 125 GeV Higgs observed at the LHC.

Contribution

Findings

Model extends the traditional top seesaw with bottom quark incorporation

Abstract

We propose a top and bottom seesaw model with partial composite top and bottom quarks. Such composite quarks and topcolor gauge bosons are bound states from supersymmetric strong dynamics by Seiberg duality. Supersymmetry breaking also induces the breaking of topcolor into the QCD gauge coupling. The low energy description of our model reduces to a complete non-minimal extension of the top seesaw model with bottom seesaw. The non-minimal nature is crucial for Higgs mixings and the appearance of light Higgs fields. The Higgs fields are bound states of partial composite particles with the lightest one compatible with a 125 GeV Higgs field which was discovered at the LHC.
