摘要
We Suggest an NMSSM scenario, motivated by dark matter constraints, that may disguise itself as a much simpler mSUGRA scenario at the LHC. We show how its non-minimal nature can be revealed, and the bino-singlino mass difference measured, by looking for soft leptons. (c) 2009 Elsevier B.V. All rights reserved.
