Abstract ​

ColliderML introduces an open dataset of one million fully simulated proton-proton collisions under High-Luminosity Large Hadron Collider (HL-LHC) conditions. Unlike existing fast-simulation datasets operating on high-level objects, ColliderML provides detector-level measurements across ten physics processes, including hits, energy deposits, and reconstructed tracks from realistic detector geometry under high luminosity pile-up conditions (µ ≈ 200). This work argues that foundation models trained on such low-level data represent the future of collider physics, positioning ColliderML as the infrastructure to realize this vision.

Getting the Data ​

The ColliderML dataset is available through a lightweight library, accessing a NERSC Public Portal. For instructions on downloading and using the data, please visit the ColliderML homepage.
