Analysis framework integrated with the FCC analysis software

FCCAnalyzer

Analysis framework integrated with the FCC analysis software

This analysis code uses class definitions, functions and modules of the main FCC analysis framework, as described here: https://github.com/HEP-FCC/FCCAnalyses.

Setup

Fork FCC analysis repo: https://github.com/HEP-FCC/FCCAnalyses

Fork this repo https://github.com/jeyserma/FCCAnalyzer

Clone the repository with the FCCAnalyses as submodule:

git clone --recurse-submodules [email protected]:jeyserma/FCCAnalyzer.git

The FCC analysis software has to be compiled once at the first time (or when any changes have been done in that actual code) as explained in the FCCAnalyses readme.

cd FCCAnalyses
source ./setup.sh
mkdir build install
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=../install
make install
cd ..

Note: by default the newest Key4Hep release is loaded, therefore sometimes one needs to re-compile FCCAnalyses framework scripts according to the steps above.

To use the FCCAnalyzer, just source the setup bash script:

source ./setup.sh

Combine environment

Combine requires either CMSSW or can be compiled standalone, but is not compatible with the newest ROOT version, as required for the main analysis with RDataFrame. Therefore, in order to run Combine, one has to load a different environment.

To install Combine (in the FCCAnalyzer directory), execute the following steps:

git clone https://github.com/cms-analysis/HiggsAnalysis-CombinedLimit.git --branch 112x HiggsAnalysis/CombinedLimit
cd HiggsAnalysis/CombinedLimit/
source env_standalone.sh
make -j ${nproc}
cd ../../

In order to run Combine, source the following script (instead of setup.sh):

source ./initCombine.sh
