Ai_tutorial

Quick plotting utilities for Ai.

Files

• AIW.C: macro used to produce the reference Ai for the MC.
• AIZ.C: related plotting macro.
• TUTORIAL.md: tutorial notes for running the workflow.

Reference Input

The reference Ai for the MC (AI_WWm_Wai_finalbinning_newSignPhowegNEW_pT_NormXsec.root) is produced on NAF in:

/nfs/dust/atlas/user/ludovica/CraigMacro

using the AIW.C macro.

Run AIZ (ROOT + TLVUtils)

1) Activate ROOT environment

conda activate MAC

2) Go to the tutorial folder

cd /Users/dudu/Downloads/Low_muRun/WAi/predictions_for_W_Ai_13TeV/Phoweg_Sherpa_comparisonPLOTs/Tutorial_AI

3) Run in ROOT (recommended interpreted mode)

root -l

Then inside ROOT:

.L TLVUtils.cxx
.L AIZ.C
test = true;      // optional: quick run
AIZ(false);       // pT binning
// AIZ(true);     // |y| binning

4) One-line batch command (no interactive ROOT prompt)

conda run -n MAC root -l -b -q -e '.L TLVUtils.cxx' -e '.L AIZ.C' -e 'test=true;' -e 'AIZ(false);' -e '.q'

Notes

• AIZ.C now includes TLVUtils.h and calls TLVUtils::getCSFAngles and TLVUtils::getAiPolynoms, so load TLVUtils.cxx before running AIZ.
• In this environment, interpreted loading is reliable. ACLiC mode with + (.L TLVUtils.cxx+) may fail due a local shared-library loading issue on macOS/conda.

Build/Run with Makefile

The repository now includes a simple Makefile with these targets:

• libs: builds TLVUtils.o and libTLVUtils.so
• run: runs AIZ(false)
• run-y: runs AIZ(true)
• run-test: runs a quick test (test=true; AIZ(false);)
• clean: removes built objects/libraries

Examples:

conda run -n MAC make libs
conda run -n MAC make run-test
conda run -n MAC make run
