| Thema: | Combining Graph Neural Networks for Track Reconstruction in Very High Backgrounds |
| Zusammenfassung: | Graph Neural Networks (GNNs) have proven to be powerful tools for track reconstruction in high-energy physics experiments, particularly in environments with complex event topologies. However, in events with extremely high background levels, distinguishing signal tracks from noise remains a significant challenge. This project aims to enhance track reconstruction by combining two different types of GNN architectures. You will first apply interaction networks to filter background noise. The cleaned events will be used to train variants of the CATFinder developed in our group. Your work will focus on optimizing this hybrid approach, improving robustness against background noise, and enhancing tracking efficiency. |

| Thema: | GNN-Based Track Reconstruction in the Silicon Pixel Detector of Belle II |
| Zusammenfassung: | The Belle II Pixel Detector (PXD), located closest to the interaction point, presents unique challenges due to its small pixels and extreme background conditions. Efficient track reconstruction in this environment is crucial for precise vertex determination in Belle II. This project will extend the CATFinder ) to incorporate information from the high-resolution PXD. You will develop a GNN-based approach that integrates PXD data into the existing tracking framework, optimizing it for the high-occupancy conditions near the beam pipe. Your work will focus on improving robustness against background hits, refining pattern recognition, and enhancing overall tracking efficiency in the inner detectors of Belle II. |

| Thema: | Automated process monitoring with workflow management software towards sustainable computing |
| Zusammenfassung: | In High Energy Physics many calculations are done on complex data. Since every calculation increases energy consumption, it is important to do these as sensible and efficient as possible. While some computing sites already provide data on the power usage of these calculations, it is still difficult to monitor the energy consumption of whole analysis workflows. In this project, an existing workflow management based on the software luigi will be extended to automatically collect data on the energy usage of its tasks. |
