Jet tagging is the process of identifying the type of elementary particle that initiates a "jet", i.e., a collimated spray of outgoing particles. It is essentially a classification task that aims to distinguish jets arising from particles of interest, such as the Higgs boson or the top quark, from other less interesting types of jets.

This work proposes ParticleNet, a customized neural network architecture using Dynamic Graph Convolutional Neural Network for jet tagging problems that achieves state-of-the-art performance on two representative jet tagging benchmarks and is improved significantly over existing methods.
OE, in the context of jet tagging, is employed to facilitate two goals: increasing sensitivity of outlier detection and decorrelating jet mass, and is observed to facilitate excellent results from both aspects.
This article introduces LundNet, a novel jet tagging method which relies on graph neural networks and an efficient description of the radiation patterns within a jet to optimally disentangle signatures of boosted objects from background events, showing significantly improved performance for top tagging compared to existing state-of-the-art algorithms.
A modified transformer network called point cloud transformer is applied as a method to incorporate the advantages of the transformer architecture to an unordered set of particles resulting from collision events to compare the performance with other strategies.
A new Transformer-based architecture for jet tagging, called Particle Transformer (ParT), which achieves higher tagging performance than a plain Transformer and surpasses the previous state-of-the-art, ParticleNet, by a large margin.
This work investigates the classifier response to input data with injected mismodelings and probes the vulnerability of flavor tagging algorithms via application of adversarial attacks and presents an adversarial training strategy that mitigates the impact of such simulated attacks and improves the classifiers robustness.
The decision-making process for one such state-of-the-art network, ParticleNet, is explored by looking for relevant edge connections identified using the layerwise-relevance propagation technique.
Adding a benchmark result helps the community track progress.
