This page was created during the DPF2013 studies. All truth-level MC samples have been moved to [[http://atlaswww.hep.anl.gov/hepsim/ | the HepSim Monte Carlo repository]] ===== Fast Monte Carlo simulation for Snowmass2013 ===== Here are top-quark "signal" samples generated by requests for Snowmass 2012-2013. Samples are generated using ANL ATLAS Tier3 computer farm based on [[http://atlaswww.hep.anl.gov/asc/arcond/ |Arcond/Condor]]. Details about the Delphes samples for Snowmass are given in [[http://www.snowmass2013.org/tiki-index.php?page=Energy_Frontier_FastSimulation| this wiki]]. * [[https://cp3.irmp.ucl.ac.be/projects/delphes | Delphes 3.09]]. Use Delphes 3 reference [[http://arxiv.org/abs/1307.6346]] * 14 TeV pp collision energy. * The Snowmass detector geometry [[http://mc.hep.anl.gov/asc/snowmass2013/delphes36/?dir=packages | See "updateMay8" input cards]] * PFlow jets with jet area correction. * Each sample is generated for **=0,50,140 pileup** pileup scenarios (soft events are generated with HERWIG++) One can view and browser directories with all simulated samples using the [[http://mc.hep.anl.gov/asc/snowmass2013/delphes36/| ANL Monte Carlo repository]].

You should apply a k-factor to get a correct normalization (can be a phase-space dependent).** Background samples are discussed in [[http://www.snowmass2013.org/tiki-index.php?page=NPBackgroundSamplesTwiki|Background Samples Twiki]]. Last re-processing was on June 8 using Delphes 3.09, 2013 (fixed bug for mu=0 samples). We did not change directory file names to make the output consistent with the download scripts ===== Truth MC records==== Truth MC record was removed from the Delphes files to reduce file size. Below you can find a repository with truth MC information: signal, signal+pileup (=50) and signal+pileup(=140). Pileup particles are included. **[[snowmass2013:montecarlo_truth | Repository with truth MC information]]** **[[http://atlaswww.hep.anl.gov/hepsim/ | HepSim Repository with Monte Carlo predictions for HEP]]** New ===== Help for analyzers==== * **[[snowmass2013:download| How to download]]** link shows an automatic way of copying the ROOT files from this server * **[[snowmass2013:analyse_d3| How to analyze]]** link explains how to analyze Delphes3 ROOT files * **[[snowmass2013:analyse_d36_promc| How to read Delphes data without ROOT]]** link explains how to analyze Delphes outputs without ROOT (and C++) * **[[snowmass2013:howto_d3| How to generate MC samples]]** link explains how to generate fast simulation events with pileups * **[[snowmass2013:howto_d3_objects| How to access objects]]** link explains how to access jets, leptons, missing ET ===== Help for Delphes developers ===== You can add a new deatures to Delphes using this test HEPMC record.
