CMS HLT@Phase2 Tracking Confgurations

This repository contains the instructions to run

The old configs and workflows used for the Upgrade DAQ and HLT TDR in 2022 are under the tdr_master branch. In this branch we "restart" the setup in a more sensible way.

To setup your cmssw to have the ingredients to run the upgrade hlt tracking configs start with

scram p -n cmssw CMSSW_13_2_0_pre2
cd cmssw/src
cmsenv
git cms-merge-topic cms-hlt-upgrade-trk:phase2_hlt_tracking_132
scram b -j 4

Apply the following changes to HLTrigger/Configuration/python/customizePhase2HLTTracking.py

This is needed to run the customization to include Patatrack pixel tracks, these changes should be soon included in cms-hlt-upgrade-trk:phase2_hlt_tracking_132

At the moment this has been tested with 13_2_0_pre2

Baseline Tracking Configuration

To run the baseline tracking configuration you can derive it from the simplified HLT menu in the release (since 12_3_X) and customizing it to run only tracking + tracking validation:

cmsDriver.py Phase2 -s HLT:75e33 \
    --processName=HLTX \
     --conditions 131X_mcRun4_realistic_v5  \
     --geometry Extended2026D95 \
     --era Phase2C17I13M9 \
     --eventcontent FEVTDEBUGHLT \
     --filein=/store/mc/Phase2Spring23DIGIRECOMiniAOD/TT_TuneCP5_14TeV-powheg-pythia8/GEN-SIM-DIGI-RAW-MINIAOD/PU200_Trk1GeV_131X_mcRun4_realistic_v5-v1/30000/01607282-0427-4687-a122-ef0a41220590.root \
     -n 10 \
     --nThreads 10 \
     --customise HLTrigger/Configuration/customizePhase2HLTTracking.customisePhase2HLTForTrackingOnly,HLTrigger/Configuration/customizePhase2HLTTracking.addTrackingValidation

Note that:

• if you want to run the whole menu skip the customisePhase2HLTForTrackingOnly customizer; [not working at the moment]
• if you don't want to run the validation skip addTrackingValidation customizer.

If you want to explore all the modules used run:

edmConfigDump Phase2_HLT.py > HLT_75e33_cfg.py

Once it runs, if you have run the validation with addTrackingValidation, you may run the harvesting with

harvestTrackValidationPlots.py Phase2HLT_DQM.root -o plots.root

and the plotter with

makeTrackValidationPlots.py plots.root

Patatrack Single Iteration (WIP)

At the moment only a single iteration approach has been implemented in which the all the pixel tracks (including triplets) are produced and used as input for the initialStep tracks while the highPtTriplet step is dropped. To run it use

cmsDriver.py Phase2_Patatrack -s HLT:75e33 \
    --processName=HLTX \
     --conditions 131X_mcRun4_realistic_v5 \
     --geometry Extended2026D95 \
     --era Phase2C17I13M9 \
     --eventcontent FEVTDEBUGHLT \
     --filein=/store/mc/Phase2Spring23DIGIRECOMiniAOD/TT_TuneCP5_14TeV-powheg-pythia8/GEN-SIM-DIGI-RAW-MINIAOD/PU200_Trk1GeV_131X_mcRun4_realistic_v5-v1/30000/01607282-0427-4687-a122-ef0a41220590.root \
     -n 10 \
     --nThreads 10 \
     --customise HLTrigger/Configuration/customizePhase2HLTTracking.customisePhase2HLTForTrackingOnly,HLTrigger/Configuration/customizePhase2HLTTracking.customisePhase2HLTForPatatrack,HLTrigger/Configuration/customizePhase2HLTTracking.addTrackingValidation
