Long lived charginos in Natural SUSY?
Long lived charginos in Natural SUSY?
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 the lightest neutralino has also been raised. Recently, the absence of any supersymmetric signal in the 8 TeV LHC …
