TZWi

Yet another CMS NanoAOD tools focusing on specific analyses.

• Management area: https://app.asana.com/0/1115311953973868/list

We'd like to cover:

• ttbar dilepton analysis
  • inclusive cross section, differential cross section
  • ttbar+bbbar cross section ratio to ttbar+jets
• ttbar rare decays
  • t->qZ, ttbar and single top

(Optional) Customized NanoAOD production

cd TZWi/NanoAODProduction/test
./generateConfig.sh ## This will produce 3 sets of 3 cfg files...
crab submit...

List up NanoAOD samples

Update sample list, produce file lists

tzwi-updatedataset $CMSSW_BASE/src/TZWi/NanoAODProduction/data/datasets/NanoAOD/2016/*.yaml
tzwi-updatedataset $CMSSW_BASE/src/TZWi/NanoAODProduction/data/datasets/NanoAOD/2017/*.yaml

Run postprocessors

Assume we are working at KISTI Tier2/3 and cms-kr/hep-tools package is installed.

./01.1_submit.py

Wait for the jobs to be finished, check output files, resubmit failed jobs.

Tip to list up failed job and resubmit them:

./01.2_checkFailed.sh

You can process failed ones manually:

cat failed.txt | sed 's;nano_postproc.py;;g' | xargs -P$(nproc) -L1 nano_postproc.py

Tip to extract all ntuples:

find *NANOAOD*/ -name 'result_*.tgz' | awk '{print "xzf "$1" ./ntuple"}' | xargs -L1 -P$(nproc) tar

Make histograms

This step will draw all histograms including systematics variations using maximum 20 CPUs in parallel.

./02_make_histograms.py

To the plotting steps

Run the followings

./03_scalemerge.py
./04_drawPlots.py

Then you will have plots in "plots" directory.
