 ## November 29, 2023: Particle Physics challenge trial
 
-We will be hosting a hackathon at the [Artificial Intelligence and the Uncertainty Challenge in Fundamental Physics](https://indico.cern.ch/event/1067246/) workshop on Wednesday November 29, 2023. We are planning to release a tiral version of a challenge using detailed physics simulations of accelerator data. More information about the dataset and challenge will be released here closer to the date.
