Phenomenological aspects of supersymmetric composite Higgs models

TL;DR

This paper explores supersymmetric composite Higgs models based on the SO(5)/SO(4) coset, identifying new particles relevant for LHC searches, and discusses flavor physics constraints within a minimal flavor violation framework.

Contribution

It introduces a detailed analysis of supersymmetric pseudo Nambu-Goldstone Higgs models with matter in the fundamental representation, including new states and reinterpretation of experimental bounds.

Findings

Lightest colored particles are fermionic and scalar top partners below 1 TeV.

Standard Model quark masses can arise from dimension five operators in a non-minimal flavor violating setup.

Experimental bounds on new states are consistent with the model's predictions.

Abstract

We study previously introduced models of pseudo Nambu-Goldstone boson Higgs from linearly realized minimal coset SO(5)/SO(4) and matter in the fundamental in supersymmetric theories. Partial compositeness is at work for top and electroweak gauge fields. New states potentially relevant for LHC signatures are identified and we show how to reinterpret existing experimental results as exclusion bounds. The lightest colored particles, with a mass below the TeV, are fermionic and scalars top partners. We outline a viable mechanism originating masses of other Standard Model quarks: they result from the generation of dimension five operators in a non minimal flavor violating context. We study the impact of such operators on flavor processes and we show how experimental bounds are satisfied.
