Mixing Signal Events into Heavy Ion Background

Instructions for generating, simulating and mixing signal event

Quick Instructions

Heavy Ion mixing job can be created in two ways, by either using cmsDriver.py command, or writing a cfg yourself.

Using cmsDriver.py

Writing a custom configuration

Create a PoolSource that opens an input (heavy ion background) file.

Load a generator particularly configured for mixing:


Or, define a generator module from scratch:

process.hiSignal = cms.EDFilter('PyquenProducer',....)

Load the heavy ion mixing module:


Add the sequence as a first thing to run in a path, or the first path to run in a schedule.

process.signal_step = cms.Path(process.hiSignalSequence)

Step by step Instructions







Production Instructions


Here are instruction for setting up a CMSSW project area that is capable to run the event embedding configurations. For detailed help on the steps involved, please consult the WorkBook, or MIT Tier-2/3 user guide for running locally at MIT.


  • Setup your CMSSW area and environment
  • Setup you CVSROOT and get your kerberos 5 token
  • Execute the following:
     cvs co UserCode/CmsHi/Utilities/scripts/setup33X.sh

Running with Crab
