Python package for the Energy Flow suite of particle physics tools

Project description


alt-text Binder

EnergyFlow is a Python package that computes Energy Flow Polynomials (EFPs) as defined in Ref. [1], implements Energy Flow Networks (EFNs) and Particle Flow Networks (PFNs) as defined in Ref. [2], computes Energy Mover's Distances as defined in Ref. [3], and provides access to some particle physics datasets hosted on Zenodo including the jet datasets in MOD HDF5 format used in Ref. [4].


To install EnergyFlow with pip, simply execute:

pip install energyflow
