Search for R-parity violating supersymmetry with the ATLAS detector

TL;DR

This paper reports on searches for R-parity violating supersymmetry signatures using the ATLAS detector at the LHC, focusing on resonant sneutrino decays and displaced vertices from heavy particle decays, based on 7 TeV collision data.

Contribution

It presents the first ATLAS search results for R-parity violating supersymmetry involving resonant and displaced decay signatures.

Findings

No significant excess observed over Standard Model predictions.

Set new limits on R-parity violating SUSY parameter space.

Demonstrated the ATLAS detector's capability to search for complex SUSY signatures.

Abstract

R-parity violation in supersymmetry gives rise to many unique experimental signatures. We describe searches with the ATLAS detector for supersymmetry with R-parity violating decays. Examples include searches for resonant sneutrino decays to an electron and a muon, and displaced vertices arising from the late decays of heavy objects with a muon in the final state. The most recent results on these channels are presented based on data recorded with the ATLAS detector in 7TeV proton-proton collisions at the CERN Large Hadron Collider in 2010 and 2011.
