Anomaly detection with Convolutional Graph Neural Networks
Oliver Atkinson, Akanksha Bhardwaj, Christoph Englert +2
We devise an autoencoder based strategy to facilitate anomaly detection for boosted jets, employing Graph Neural Networks (GNNs) to do so. To overcome known limitations of GNN auto…

On interference effects in top-philic decay chains
Oliver Atkinson, Christoph Englert, Panagiotis Stylianou
Sizeable exotic Higgs boson production through gluon fusion via top quark loops is correlated with large Higgs decay probabilities into top quark final states, if these are kinemat…
