Signals of doubly-charged Higgsinos at the CERN Large Hadron Collider. Physical Review D - Particles, Fields, Gravitation and Cosmology, 78(3). doi:10.1103/PhysRevD.78.0350131550-79981550-23681550-7998http://doi.org/10.1103/PhysRevD.78.035013https://hdl.handle.net/11147/2156Several supersymmetric models with extended gauge structures, motivated by either grand unification or by neutrino mass generation, predict light doubly-charged Higgsinos. In this work we study productions and decays of doubly-charged Higgsinos present in left-right supersymmetric models, and show that they invariably lead to novel collider signals not found in the minimal supersymmetric model or in any of its extensions motivated by the μ problem or even in extra dimensional theories. We investigate their distinctive signatures at the Large Hadron Collider in both pair- and single-production modes, and show that they are powerful tools in determining the underlying model via the measurements at the Large Hadron Collider experiments. © 2008 The American Physical Societyeninfo:eu-repo/semantics/openAccessCERN Large Hadron Collider (LHC)Supersymmetric modelsHiggs fieldArticle2-s2.0-5084911177410.1103/PhysRevD.78.035013
