Vector Boson Scattering Analysis Framework

Preselection Framework

Directory Structure

• src/: Contains the source code for the preselection framework.
• include/: Contains the header files miscellaneous imports.
• etc/: Contains configuration scripts and JSON files for defining inputs.
• bin/: Directory where the compiled binary will be placed.
• build/: Directory where the object files will be placed.

Prerequisites

• ROOT
• GCC compiler
• Python 3.x
• Uproot
• Boost library (for GoldenJSON)

Compilation

To compile the preselection framework, navigate to the preselection directory and run:

make

This will compile the source files and place the binary in the bin/ directory.

---

Configuration

The inputs for the preselection framework are defined using JSON files. The make-config.py script in the etc/ directory is used to generate these JSON configuration files, specifics will have to be adapted by the analyzer.

Generating Configuration Files

To generate a configuration file, run the make-config.py script with the appropriate category (bkg, sig, or data):

python3 etc/make-config.py --category <category>

For example, to generate a configuration file for background samples:

python3 etc/make-config.py --category bkg

This will create a JSON file in the etc/ directory with the necessary configuration for the specified category.

---

Running the Preselection

To run the preselection, use the compiled binary and provide the input specification and output file:

bin/runAnalysis --spec <input_spec> --output <output_file>

Command Line Arguments:

--spec: Path to the JSON configuration file defining the input specification.
--output: Path to the output file where the results will be saved.
--nthreads: Number of threads to use for parallel processing (optional).
