Extending the Reach of Searches for Staus, Charginos and Neutralinos with the ATLAS Experiment at the Large Hadron Collider
… three types of supersymmetric particles; staus, charginos and neutralinos, using the 139 fb⁻¹ of data collected with the ATLAS experiment at the Large Hadron Collider between 2015 and 2018. Searches for three different production modes of these particles are considered, with new approaches for …

Search For Trilepton Resonances From R-Parity Violating Chargino Decays In The B−l Mssm
… a search for the electroweak pair-production of charginos and the associated production of charginos and neutralinos in the B−L Minimal Supersymmetric Standard Model with spontaneous R-parity violation. The chargino and neutralino each decay via R-parity violating couplings to a charged lepton or …

CP violation in production and decay of supersymmetric particles
… und Zwei-Teilchen-Zerfaellen von Neutralinos, Charginos und Sfermionen. Fuer verschiedene supersymmetrische Prozesse definieren und berechnen wir CP-ungerade Asymmetrien, welche auf Spatprodukten basieren. Wir zeigen numerische Ergebnisse fuer Elektron-Positron-Kollisionen an einem zukuenftigen …

Symbolic computation of electron-proton to slepton-squark scattering cross sections based on a left-right supersymmetric extension of the standard model
… from the t-channel exchange of neutralinos and charginos in electron-proton scattering is analyzed. The symbolic programming language Mathematica ® , is used to develop a program to generate a symbolic representation of the invariant amplitude for these processes. Differential cross sections, …

First search for electroweak supersymmetry in final states with hadronic decays of WW, WZ, or WH boson pair and missing transverse momentum.
… of supersymmetric particles, specifically charginos and neutralinos. The novel search is performed using Run 2 data from the CMS experiment at the LHC with a total integrated luminosity of 137 fb−1 . The targeted final states include a pair of bosons (WW, WZ, or WH) with large missing …

A Search for Sleptons with Intermediate Lifetimes in e+e- Collisions at sqrt(s)=189-209 GeV
… Produktion ueber Paar-Erzeugung von Neutralinos, Charginos und, im Falle des Staus, Selektronen und Smyonen) wurden beruecksichtigt. In dem untersuchten Datensatz bei sqrt(s)=189-209GeV mit einer integrierten Luminositaet von etwa 600 pb^(-1) wurde keine Evidenz fuer die Existenz von Sleptonen mit …

Enhancing the sensitivity of the ATLAS experiment to electroweak supersymmetry
… orthogonal searches for the pair-production of charginos is performed. This extends and deepens the existing sensitivity and exclusion power offered by each analysis alone. Finally, a machine learning method is presented to improve the reconstruction performance of missing transverse momentum …

Machine learning based searches for new physics at the ATLAS experiment
… Exclusion limits are set on the masses of the charginos and neutralinos, which cover an important gap in sensitivity between previous searches. Secondly, a novel method for performing model-independent searches for parity-violating new physics is presented. This analysis method uses …

TRACKING THE INVISIBLE. A SEARCH FOR SUPERSYMMETRIC HIGGSINOS WITH THE ATLAS DETECTOR.
… and Run 3. The analyses target the production of charginos and neutralinos near the electroweak scale and with mass splittings in the range $0.3-1.5$ GeV. Owing to the small mass differences, the heavier neutralino and chargino are relatively long-lived and decay into low-momentum charged pions, …
