| Title | Domain-Adversarial Graph Neural Networks for Lambda Hyperon Identification with CLAS12 | ||||
| Abstract | Machine learning methods and in particular Graph Neural Networks (GNNs) have revolutionized many tasks within the high energy physics community. We report on the novel use of GNNs and a domain-adversarial training method to identify ? hyperon events with the CLAS12 experiment at Jefferson Lab. The GNN method we have developed increases the purity of the ? yield by a factor of 1.95 and by 1.82 using the domain-adversarial training. This work also provides a good benchmark for developing event tagging machine learning methods for the ? and other channels at CLAS12 and other experiments, such as the planned Electron Ion Collider. | ||||
