ETX4VELO#
The ETX4VELO repository is an attempt in using Graph Neural Networks (GNN) to perform track finding at LHCb. It is based on the pipeline developed by the Exa.TrkX collaboration. It has undergone refinements tailored to the forwardness nature of LHCb and the specific track topology of interest.
The pipeline was presented during a WP2 reconstruction meeting on the 12th of September, 2023.
Danger
Please be aware that the ETX4VELO repository currently lacks flexibility in its pipeline configuration. As of now, it does not support the ability to define or remove steps within the pipeline. While you can customize most of the network parameters by modifying the pipeline configuration YAML file, please note that not all parameters are guaranteed to function as expected.
Note
If you are looking for a swift introduction to a GNN-based pipeline for track finding, you might find the Exa.TrkX guide to be a more suitable resource. Alternatively, a guide to train our pipeline is available under Training a Pipeline.
