17 | // Implementation of a branch replicator | |
18 | // to produce aods with only few branches. | |
19 | // | |
20 | // This replicator is in charge of replicating the nuclei primary vertices | |
21 | // tracks identified as nuclei with Z>=2, secondary vertices in form of | |
22 | // AliAODRecoDecayLF2Prong and their daughter tracks. | |
23 | // These informations are stored into a reduced AODs (AliAOD.NuclEx.root) | |
24 | // | |
25 | // The vertices are filtered so that only the primary vertices make it | |
26 | // to the output aods. | |
27 | // | |
28 | // The secondary vertices are recreated here, as a AliAODRecoDecayLF2Prong | |
29 | // plus cuts that select secondary vericesoutside the primary vertex | |
30 | ||
31 | // Authors: S. Bufalino (stefania.bufalino@cern.ch) | |
32 | // R. Lea (ramona.lea@cern.ch) | |
33 | // Based on AliAODMuonReplicator.cxx | |
34 | ||
35 | //NOTE : This is a test on MC : no PID response only MC truth + select only 3LH | |
36 | // daughters : NOT INTENDED for any efficiency!! | |
