Learn some physics behind this short analysis

Prerequisite setup¶

Example Analyses are separated into these files:

processor_<example_name>.py
runner_<example_name>.py
plotter_<example_name>.py

A. Clone the coffea-fcc-analyses repository.

B. cd coffea-fcc-analyses

ZH Recoil Example:¶

Navigate to example folder
```
cd examples/FCCee/higgs/mHrecoil/mumu/
```
Start the singularity shell
```
./shell
```
A] Local Execution

Within the shell execute runner_mHrecoil.py with the desired parameters(–executor or -e set to dask by default). The output file would be saved at ./output/FCCee/higgs/mH-recoil/mumu/.
```
singularity> python3 runner_mHrecoil.py -e dask
```
One can also choose to split up the processing and results in chunks with the –chunks or -c argument
```
singularity> python3 runner_mHrecoil.py -e dask -c 8
```
B] Batch Execution with HTCondor

Choosing the executor as condor one can generate job and submit files and a master submit file called condor.sh
```
singularity> python3 runner_mHrecoil.py -e condor -c 8
```
Now exit the container shell with exit , move to the directory where the files are created(by default Batch) and run condor.sh without getting into the shell
```
singularity> exit
cd Batch
./condor.sh
```
Generate plots with plotter_mHrecoil.py (from the singularity shell). The plots would be saved at ./output/FCCee/higgs/mH-recoil/mumu/plots/
```
singularity> python3 plotter_mHrecoil.py
```
If the plots are generated in a different folder than ./output/FCCee/higgs/mH-recoil/mumu/ , input it’s path with the –input or -i keyword. For example for batch submission, the outputs are saved in Batch directory.
```
singularity> python3 plotter_mHrecoil.py -i Batch
```
