13 | /// Compact information for the muon generated tracks in the MUON arm | |
14 | /// useful at the last stage of the analysis chain | |
15 | /// provides a link between the reconstructed track and the generated particle | |
16 | /// stores kinematical information at gen. and rec. level and | |
17 | /// the decay history of the muon, allowing the identification of the | |
18 | /// mother process | |
