Here are samples of Delphes 3.05 events generated for the 14 TeV center-of-mass energy (pp collisions). The events are generated for 0 pileup, 50 and 140 pileup scenarios.
All data are stored in the ROOT format using the standard Delphes 3.05 output. Therefore, it is recommended to install Delphes 3.0.5 and look at the example explaining how to read such ROOT files (see the directory “Examples” inside the Delphes package).
The samples use the ATLAS detector geometry located in “examples/delphes_card_ATLAS.tcl” of the Delphes 3.05 installation. We use “towers” to build antiKT4 jets.
The truth information from the signal MC shown above was used to overlay with 50 pile up events (fixed number, not “Poisson” case!) The events were overplayed at the HEPMC true level (thanks to Andy Buckley for his help and http://pilemc.hepforge.org/ tool), and then were processed using Delphes 3.05.

In total, there are 200 Zprime (mass=3000 GeV) events per one file.
Look at the log files of PYTHIA8 and Delphes for this runs:

In total, there are 96 files, with 200 ttbar events in each. Thus the total number of events is 19200 signal events.

To reduce ROOT file size, truth information in these ROOT files was slimmed. Please read here.
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
