Description

We present a versatile GNN-based end-to-end reconstruction algorithm for highly granular calorimeters that can include track and timing information to aid the reconstruction of particles. The algorithm starts directly from calorimeter hits and possibly reconstructed tracks, and outputs a coordinate transformation in which all shower objects are well separated from each other and assigned properties such as particle momenta and ID in one go.
We showcase the versatility of this approach by presenting its application to a detector that matches the complexity of the CMS high-granularity calorimeter, an ATLAS-like setting as well as future collider detectors.
