Key Points
Introduction
- Track-cluster is a critical part of reconstructing particles
- Truth-reconstructed matching is needed to validate reconstructed particles
Using PODIO to Work With Our Data Model
- A data model is how represent our data in software
- PODIO is a toolkit to generate and interface with data models like EDM4eic
- Classes have their accessors prefixed by get/set, components don’t
- Relations are references to objects in other collections
- Associations/links define indirect connections between objects
Track-Cluster Matching
- We can match tracks to clusters based on distances in eta-phi space
- Care is needed to make sure you’re picking out the relevant cluster
- Electrons can be identified with an E/p cut
- J/psi can be reconstructed by considering pairs of reconstructed electrons
Parent-Daughter Matching
- J/psi are measured as dileptons, pairs of decay leptons
- Need to track which J/psi decayed to which electrons and their associated tracks
