Large Sample WW and ZZ data

hshaddix · April 28, 2022, 10:15pm

At the moment me and my research advisor are looking at e+e- to Higgs and pseudo-Higgs production and we wanted to compare the data to the standard model generated WW and ZZ background decays. Are there any places besides (or like) /eos/experiment/fcc/ that would have data generated at a larger scale? It seems the eos pathway above only has WW and ZZ decays with around 50,000 events or so.

Thanks,
Hayden Shaddix

Dear @hshaddix ,

according to
http://fcc-physics-events.web.cern.ch/fcc-physics-events/Delphesevents_spring2021_IDEA.php
we have 10 millions of p8_ee_WW_ecm240 and p8_ee_ZZ_ecm240, not sure where your number is coming from, maybe because you only use a fraction of the full smaple?

Dr. @clement.helsens ,

You are right. I did not see these and they are what I was looking for.
Also, is there a tutorial or some kind of example of using those eos sample sets and creating histograms as in the FCC tutorial kit? They are large enough that it is not viable for me to use my home directory, but I am not finding anything.

Thanks,
Hayden Shaddix

Dear @hshaddix ,

sorry for the late reply here.
to use a large sample, you could have a look at this example:

github.com

HEP-FCC/FCCAnalyses/blob/master/examples/FCCee/higgs/mH-recoil/mumu/analysis_stage1.py

#Mandatory: List of processes
processList = {
    'p8_ee_ZZ_ecm240':{},#Run the full statistics in one output file named <outputDir>/p8_ee_ZZ_ecm240.root
    'p8_ee_WW_ecm240':{'fraction':0.5, 'chunks':2}, #Run 50% of the statistics in two files named <outputDir>/p8_ee_WW_ecm240/chunk<N>.root
    'p8_ee_ZH_ecm240':{'fraction':0.2, 'output':'p8_ee_ZH_ecm240_out'} #Run 20% of the statistics in one file named <outputDir>/p8_ee_ZH_ecm240_out.root (example on how to change the output name)
}

#Mandatory: Production tag when running over EDM4Hep centrally produced events, this points to the yaml files for getting sample statistics
prodTag     = "FCCee/spring2021/IDEA/"

#Optional: output directory, default is local running directory
outputDir   = "outputs/FCCee/higgs/mH-recoil/mumu/stage1"

#Optional: ncpus, default is 4
#nCPUS       = 8

#Optional running on HTCondor, default is False
#runBatch    = False

#Optional batch queue name when running on HTCondor, default is workday

This file has been truncated. show original

that could be run (using a local installation) with python config/FCCAnalysesRun.py examples/FCCee/higgs/mH-recoil/mumu/analysis_stage1.py

In addition, I should be merging this pull request soon: Use FCCAnalysisRun for everything by clementhelsens · Pull Request #156 · HEP-FCC/FCCAnalyses · GitHub
such that the “new” worflow can be used

hope this helps.
Clement

Dear @hshaddix ,

the latest master contains now all the changes mentionned above, I suggest you pull the latest code and give it a try.

Cheers,
Clement
