Search for Squark Production in R-Parity Violating Supersymmetry at HERA
… squarks in supersymmetric models which allow R-parity violation. Electron-proton and positron-proton collisions taken at a centre of mass energy of 320 GeV have been investigated using the H1 detector at HERA. No deviation from the Standard Model has been found and exclusion limits in various …

Search For Trilepton Resonances From R-Parity Violating Chargino Decays In The B−l Mssm
… Supersymmetric Standard Model with spontaneous R-parity violation. The chargino and neutralino each decay via R-parity violating couplings to a charged lepton or neutrino and a W, Z, or Higgs boson. This analysis searches for resonances in the trilepton invariant mass spectrum, targeting events …

Suche nach R-paritätsverletzenden Zerfällen supersymmetrischer Teilchen in Endzuständen mit Jets und Leptonen mit dem OPAL-Detektor bei LEP
Von allen in den Jahren 1998 bis 2000 mit dem OPAL-Detektor am <br>e+e--Speicherring LEP am CERN aufgenommenen Daten wurden jene Ereignisse untersucht, in <br>denen geladene Leptonen und hadronische Jets nachgewiesen wurden. Dabei wurde nach Anzeichen für spezielle Zerfälle neuer Teilchen gesucht. …

Searching for long-lived particles Beyond the Standard Model with displaced vertex signatures using the ATLAS detector: Not all hopes for new physics die immediately
… best limits in this lifetime range to date on R-parity violating supersymmetry models. The second analysis uses a similar strategy, but using missing transverse energy as the trigger. This improves upon the early Run 2 2016-data search with an updated analysis strategy and a new vertexing …
