# Trilinear-Augmented Gaugino Mediation

## TL;DR

This paper explores a gaugino-mediated supersymmetry breaking model with direct Higgs coupling, leading to large stop mixing and Higgs mass, analyzing parameter space constraints with LHC data.

## Contribution

It introduces a novel scenario with Higgs coupling to supersymmetry-breaking fields, resulting in non-zero trilinear couplings and implications for Higgs mass and LHC phenomenology.

## Key findings

- Allowed parameter points with various NLSPs identified.
- Large stop mixing can achieve the observed Higgs mass.
- Constraints from LHC heavy stable charged particle searches applied.

## Abstract

We consider a gaugino-mediated supersymmetry breaking scenario where in addition to the gauginos the Higgs fields couple directly to the field that breaks supersymmetry. This yields non-vanishing trilinear scalar couplings in general, which can lead to large mixing in the stop sector providing a sufficiently large Higgs mass. Using the most recent release of FeynHiggs, we show the implications on the parameter space. Assuming a gravitino LSP, we find allowed points with a neutralino, sneutrino or stau NLSP. We test these points against the results of Run 1 of the LHC, considering in particular searches for heavy stable charged particles.
