    • Invariant Mass Distributions of SUSY Cascade Decays 

      Kvellestad, Anders (Master thesis, 2011-06-01)
      If supersymmetry (SUSY) is realised at experimental energies and R-parity is conserved, sparticles might be produced and decay in cascades at the LHC. A neutral LSP will escape detection, complicating the reconstruction ...

    • Long lived charginos in Natural SUSY? 

      Bomark, Nils-Erik; Kvellestad, Anders; Lola, Smaragda; Osland, Per; Raklev, Are (Peer reviewed; Journal article, 2014-05-05)
      Supersymmetric models with a small chargino-neutralino mass difference, and as a result metastable charginos, have been a popular topic of investigation in collider phenomenology. The possibility of a chargino lighter than ...

    • R-parity violating chargino decays at the LHC 

      Bomark, Nils-Erik; Kvellestad, Anders; Lola, Smaragda; Osland, Per; Raklev, Are (Peer reviewed; Journal article, 2014-12)
      Supersymmetric models with R-parity violation (RPV) have become more popular following the lack of any excess of missing energy events at the 8 TeV LHC. To identify such models, the suggested searches generally rely on the ...

    • Reinterpretation of LHC results for new physics: status and recommendations after run 2 

      Athron, Peter; Balázs, Csaba; Buckley, Andy; Gonzalo, Tomas Esteban; Kvellestad, Anders; Osland, Per; Raklev, Are; Scott, Pat (Journal article; Peer reviewed, 2020-08-21)
      We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental ...

    • Signal mixture estimation for degenerate heavy Higgses using a deep neural network 

      Kvellestad, Anders; Mæland, Steffen; Strümke, Inga (Peer reviewed; Journal article, 2018-12)
      If a new signal is established in future LHC data, a next question will be to determine the signal composition, in particular whether the signal is due to multiple near-degenerate states. We investigate the performance of ...
