Probing Models with Near Degeneracy of the Chargino and LSP at a Linear e+e- Collider
Abstract
For some choices of soft SUSY--breaking parameters, the LSP is a stable neutralino, the NLSP is a chargino almost degenerate in mass with the LSP (with mass difference \sim m_{\pi}-few GeV), and all other sparticles are relatively heavy. We discuss the potential of a \sqrt{s}\sim 600\gev e^+e^- collider for studying such models.
