# Light and compressed gluinos at the LHC via string theory

## TL;DR

This paper explores how string theory models, specifically large volume scenarios with D3-branes, predict light gluinos that could evade current LHC detection, linking theoretical models to experimental data.

## Contribution

It demonstrates the use of global fits of string theory parameters to low energy data to identify potential signatures of light gluinos at the LHC.

## Key findings

- LVS models predict light, quasi-degenerate gluinos and neutralinos
- Such gluinos may evade current LHC search strategies
- Global fits connect string theory parameters to observable physics

## Abstract

In this article, we show that making global fits of string theory model parameters to data is an interesting mechanism for probing, mapping and forecasting connections of the theory to real world physics. We considered a large volume scenario (LVS) with D3-branes matter fields and supersymmetry breaking. A global fit of the parameters to low energy data shows that the set of LVS models are associated with light gluinos which are quasi-degenerate with the neutralinos and charginos they can promptly decay into and thus possibly hidden to current LHC gluino search strategies.
