Detailed Description

Description: Determines the generator di-muon invariant-mass distribution

Implementation:

Generator muons are extracted from the genParticles collection and matched to Z-boson decays. The configured selection should match the selection applied on muon tracks in real data to obtain a "true" invariant mass distribution within the selection.
