Higgs Portal to Visible Supersymmetry Breaking

TL;DR

This paper introduces a supersymmetric model where the Higgs sector alone causes spontaneous supersymmetry breaking, potentially observable through new particles and dynamics in future experiments.

Contribution

It presents a novel supersymmetric extension where the Higgs sector induces SUSY breaking without hidden sectors, allowing evasion of Higgs mass bounds at tree level.

Findings

Presence of a light pseudo-goldstino in the visible sector

Additional Higgs particles from SUSY breaking dynamics

Potential for direct observation of SUSY breaking in experiments

Abstract

We propose a supersymmetric extension of the standard model whose Higgs sector induces a spontaneous supersymmetry breaking by itself. Unlike the minimal extension, the current Higgs mass bound can be evaded even at the tree-level without the help of the soft breaking terms due to the usual hidden sector, as is reminiscent of the next to minimal case. We also have a possibly light pseudo-goldstino in our visible sector in addition to extra Higgs particles, both of which stem from supersymmetry breaking dynamics. In such a setup of visible supersymmetry breaking, we may see a part of supersymmetry breaking dynamics rather directly in future experiments.
