The degenerate Wino-like chargino-neutralino scenario at a linear collider

Abstract

For some choices of soft SUSY–breaking parameters, the LSP is a stable neutralino χ10, the NLSP is a chargino χ1± almost degenerate in mass with the LSP (Δmχ1≡mχ1±−mχ10∼mπ–few GeV), and all other sparticles are relatively heavy. We discuss the potential of the NLC for studying such models.
