| 14 | === LLP with special Delphes package for MA5 === |
| 15 | |
| 16 | Delphes-LLP package is a special improvement of the Delphes package. Associated to MadAnalysis 5 v1.6, it allows the user to perform phenomenological investigations with long-lived particles or to recast existed analysis devoted to this kind of signature. |
| 17 | |
| 18 | Current status: the package handles neutral LLPs which decay into leptons in the first layers of the CMS tracker (such as neutralino in the framework of RPV-SUSY). |
