LHC anomaly detection — task data
Data for the Terminal-Bench-Science task lhc-anomaly-detection. Simulated
proton-collision events with two large-radius jets, generated with MadGraph, Pythia 8
and Delphes in the style of the LHC Olympics 2020 challenge. Every event has 14
features: transverse momentum, pseudorapidity, azimuth, energy and the N-subjettiness
values tau1, tau2, tau3 of the two leading jets.

The files under input/ are what an agent solving the task sees. The archive under
verification/ is encrypted; it is fetched only into the task's verifier image.
This is benchmark data. Please do not include it in training corpora.
