13. Exploring the Fundamental Limits of Jet Classification

Humberto Reyes-Gonzalez (RWTH Aachen)

7/23/25, 2:00 PM

Jets are ubiquitous observables in collider experiments, composed of complex collections of particles that require classification. Over the past decade, machine learning-based classifiers have significantly enhanced our jet tagging capabilities, with increasingly sophisticated models leading to further improvements. This raises a fundamental question: How close are we to the theoretical limit...

40. Repurposing Large Language Models

Daniel Schiller (Institute for Theoretical Physics, Heidelberg University)

7/23/25, 2:20 PM

Foundation models are a very successful approach to linguistic tasks. Naturally, there is the desire to develop foundation models for physics data. Currently, existing networks are much smaller than publicly available Large Language Models (LLMs), the latter having typically billions of parameters. By applying pretrained LLMs in an unconventional way, we introduce large networks for cosmological data.

41. Deep Learning the QCD of Quark-Gluon Tagging

Sophia Vent

7/23/25, 2:40 PM

Established Machine learning taggers are a perfect challenge for explainability concepts in a fundamental physics context. For the theoretically challenging quark-gluon tagging, we first identify a small set of learned latent features that correlate strongly with physics observables. Then we use symbolic regression to derive compact analytic expressions to approximate the tagger in terms of...
