# Limits on R-parity-violating couplings from Drell-Yan processes at the LHC

## TL;DR

This paper derives new constraints on R-parity violating couplings in the minimal supersymmetric standard model using Drell-Yan process data from the LHC, improving existing bounds especially at higher squark masses.

## Contribution

It provides novel limits on 12 to 13 RPV couplings using LHC Drell-Yan data, extending the bounds to higher squark masses and demonstrating potential improvements with future collider upgrades.

## Key findings

- New limits on 12-13 RPV couplings for squark masses above 1-2 TeV.
- Constraints derived from ATLAS monolepton and dilepton data.
- Potential for stronger bounds at high-luminosity LHC upgrades.

## Abstract

We find constraints on R-Parity Violating (RPV) couplings of the minimal supersymmetric standard model, using Drell-Yan differential cross sections at the LHC. Specifically, we look at the constraints on $\lambda'LQD^c$ couplings from monolepton and dilepton data published by ATLAS, with either electrons or muons in the final state. Out of the 18 RPV couplings to which the LHC is at least potentially sensitive by this technique, we find new limits on 12 (or 13) of them, for squarks masses above 1 (or 2) TeV. We also show that one can employ our techniques to achieve significantly stronger bounds at a high-luminosity upgrade of the LHC.
