Zprime(3000) to ttbar
Here are samples of Delphes 3.08 events generated for the 14 TeV center-of-mass energy (pp collisions). The events are generated for 0, 50 and 140 pileup scenarios. All data are stored in the ROOT format using the standard Delphes output. Therefore, it is recommended to install Delphes and look at the example explaining how to read such ROOT files (see the directory “Examples” inside the Delphes package). The samples use the “Snowmass” detector geometry. Jets were corrected using jet area correction and fake jets are not stored. See this wiki for details.
How to download
Please read the Section How to download. You need a python script “download.py”
Zprime(3000) signal
The samples are generated for Zprime (3 TeV) to ttbar, all decays, using PYTHIA8 (14 TeV collisions). In total, there are 96 files per sample (mu=0,50,140), with 1000 ttbar events in each. Thus the total number of events is 96000 signal events per sample.
PYTHIA8 log file is here A_RUN_signal.log.gz. This is PYTHIA8 settings.

How to analyze using ROOT
If you need to find the effect of pileup on top reconstruction or a jet measurement, you need to run the analysis code over signal MC and then over the signal+pileup MC files. Read analyse_d3
How to analyze without ROOT
In some cases, you may not have ROOT installed to read these Delphes files. In this case, you can use ROOT files converted to the ProMC format which can be read without ROOT (using C++, Java, Python). Read how to read Delphes3 output without ROOT.
