Detailed Description

Compact information for the muon generated tracks.

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

To be used together with AliMUONPairLight
