Natural Supersymmetry from the Yukawa Deflect Mediations

TL;DR

This paper proposes a Yukawa deflect mediation mechanism to realize natural supersymmetry with light third-generation squarks and a potentially large first-generation squark mass, aligning with LHC constraints.

Contribution

It introduces a novel Yukawa deflect mediation model that naturally generates the desired sparticle spectrum for natural SUSY, addressing hierarchy and experimental constraints.

Findings

First generation squarks can be large and positive in mass

The model achieves natural SUSY with light stops, sbottoms, and gluinos

Detailed phenomenology and sparticle spectrum analysis provided

Abstract

The natural supersymmetry (SUSY) requires light stop quarks, light sbottom quark, and gluino to be around one TeV or lighter. The first generation squarks can be effectively large which does not introduce any hierarchy problem in order to escape the constraints from LHC. In this paper we consider a Yukawa deflect medation to realize the effective natural supersymmetry where the interaction between squarks and messenger are made natural under certain Frogget-Nelson $U(1)_X$ charge. The first generation squarks obtain large and postive contribution from the yukawa deflect mediation. The corresponding phenomenology as well as sparticle spectrum are discussed in detail.
