On Measuring Split-SUSY Gaugino Masses at the LHC

Open full text 12 citations

Abstract

In Split-SUSY models, where the only non-Standard Model states produceable at the LHC consist of a gluino plus neutralinos and charginos (EW gauginos), it is often stated that only mass differences among these latter are measureable. The present work demonstrates that, using a Hidden Threshold technique, full reconstruction of EW gaugino masses is possible. 1
