H → μμ

This is the documentation for the H→μμ analysis — the search for the Higgs boson decaying to a muon pair, built on the FLAF framework. It is a single-Higgs analysis with the leanest FLAF setup.

The common workflow lives in the FLAF docs

H→μμ runs on FLAF, so installation, the task pipeline (NanoAOD → anaTuples → histograms → plots), the configuration system, storage, eras and CI are shared with every FLAF analysis and documented once, in the FLAF documentation:

• Prerequisites & installation
• Your first run
• Full workflow walkthrough
• Command arguments

This site covers only what is specific to H→μμ.

How H→μμ differs from the HH analyses

Aspect	H→μμ
Process	Single Higgs (H→μμ), not di-Higgs.
Submodules	The simplest set: just FLAF and Corrections.
Statistical inference	None in this repository — there is no StatInference/inference submodule.
Eras	Runs over all Run 3 eras (CI uses ALL).
CI process names	lower-case (custom_CI_signal, custom_CI_background, custom_CI_data).

Quickstart

git clone --recursive git@github.com:cms-flaf/H_mumu.git
cd H_mumu
source env.sh                                  # first time builds the environment
voms-proxy-init -voms cms -rfc -valid 192:00
law index --verbose

Then smoke-test the chain (see FLAF → first run):

law run FLAF.Analysis.tasks.HistPlotTask \
  --version my_first_run --period Run3_2022 --workflow local --branches 0 --test 1000

Eras

H→μμ runs over all Run 3 eras (Run3_2022, Run3_2022EE, Run3_2023, Run3_2023BPix, and newer as they come online). See FLAF → Eras.
