Generate a sample of particles inside a jet. Jetlib generates events through the Pythia8 event generator and clusters particles with FastJet, producing a ROOT file containing information about jets and their constituents.

To run jetlib, clone the repo and follow these steps

cd jetlib
mkdir build && cd build
cmake ..
make -jN
./jetlib -f output.root --nEvents 5

Jetlib uses fastjet-3.5.0 and pythia8.306
