# Constraining sleptons at the LHC in a supersymmetric low-scale seesaw scenario

## TL;DR

This paper investigates constraints on sleptons within a natural supersymmetry framework featuring a low-scale seesaw mechanism, analyzing how LHC data limits their masses in models with light right-handed neutrinos and higgsino-like neutralinos.

## Contribution

It introduces a supersymmetric low-scale seesaw model with light R-sneutrinos and higgsinos, and systematically evaluates LHC bounds on slepton masses in this context.

## Key findings

- LHC data constrains slepton masses in the model.
- The model accommodates light right-handed neutrinos and higgsinos.
- Constraints depend on the nature of the lightest supersymmetric particle.

## Abstract

We consider a scenario inspired by natural supersymmetry, where neutrino data is explained within a low-scale seesaw scenario. We extend the Minimal Supersymmetric Standard Model by adding light right-handed neutrinos and their superpartners, the R-sneutrinos, and consider the lightest neutralinos to be higgsino-like. We consider the possibilities of having either an R-sneutrino or a higgsino as lightest supersymmetric particle. Assuming that squarks and gauginos are heavy, we systematically evaluate the bounds on slepton masses due to existing LHC data.
