-# samples
+The event files in ROOT format in this folder where generated using MadGraph5_aMC@NLO v2.9.1.2+Pythia v8.303+Delphes v3.4.2.
+All samples are generated using MSSM_SLHA2-full modelfiles included in MadGraph. The requirement ptj1min > 200GEV is imposed at generatorm level. For each case, the squark has a mass of 1TeV and gluino 2TeV. The LSP is a neutralino of mass 995 GeV
+
+The process corresponding to each sample is described in the following
+
+(i) squarq_exclusive.root:
+generate p p > su1 go , go > su1 u~
+add process p p > su1~ go , go > su1~ u
+add process p p > su1 go j , go > su1 u~
+add process p p > su1~ go j , go > su1~ u
