# HepSim validation script using Jas4pp or hs-toolkit 
# Task: Reconstruct pT amd Mjj cross sections using ProIO input file.
#       The particle records are saved as VarintPackedParticles 
#       The validation also uses weights from Pythia8.
#       It uses a fast transform from ProIO record to ArrayList
