==== A collections of Higgs+ttbar samples ====


Here are samples of [[https://cp3.irmp.ucl.ac.be/projects/delphes | Delphes 3.08]] events generated for the **14 TeV** center-of-mass energy (pp collisions).  HEPMC files are generated by **Jahred Adelman (Yale University, jahreda@gmail.com)**. The events are generated for **0, 50 and 140** pileup scenarios. Data  are stored in the  ROOT format  using the standard [[https://cp3.irmp.ucl.ac.be/projects/delphes | Delphes]] output.
The samples use the "Snowmass" detector geometry. Jets were corrected using jet area correction and fake jets are not stored.
See [[http://www.snowmass2013.org/tiki-index.php?page=Energy_Frontier_FastSimulation| this wiki]] for details. 
 
==== How to download ROOT files====

Please read the Section [[snowmass2013:download| How to download]]. You need a python script called "download.py".

All files are located [[http://mc.hep.anl.gov/asc/snowmass2013/delphes36/?dir=jahreda| here]]
ROOT files contain reconstructed Delphes outputs, ProMC files contain original HEPMC truth record.

==== Truth record ====

ROOT Delphes files do not have complete truth records.
To view  truth record,  use  [[http://atlaswww.hep.anl.gov/asc/promc/|ProMC]] files or HEPMC files. Look at the repository [[ http://mc.hep.anl.gov/asc/snowmass2013/delphes36/promc/ | ProMC repository]], identify a file with the ".promc" extension using the description in the "logfile". Example: view complete truth-level of  Z+gamma+gamma process:
<code bash>
wget http://mc.hep.anl.gov/asc/snowmass2013/delphes36/promc/user.jahreda.028310._00001.pythia_events.promc
wget http://atlaswww.hep.anl.gov/asc/promc/download/browser_promc.jar 
java -jar browser_promc.jar user.jahreda.028310._00001.pythia_events.promc
</code>
(need Java7)

==== 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 [[snowmass2013:analyse_d3]]

==== How to analyze without ROOT ====

In some cases, you may not have ROOT installed to read the 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 
[[snowmass2013:analyse_d36_promc| how to read Delphes3 output without ROOT]].
