Machine-enhanced CP-asymmetries in the Higgs sector
Akanksha Bhardwaj, Christoph Englert, Robert Hankache +1
Improving the sensitivity to CP-violation in the Higgs sector is one of the pillars of the precision Higgs programme at the Large Hadron Collider. We present a simple method that a…
Improved Constraints on Effective Top Quark Interactions using Edge Convolution Networks
Oliver Atkinson, Akanksha Bhardwaj, Stephen Brown +3
We explore the potential of Graph Neural Networks (GNNs) to improve the performance of high-dimensional effective field theory parameter fits to collider data beyond traditional re…
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…
