12 August 2024: some registered participants have reported receiving email messages from "Global Travel Experts" or similar organizations, offering to book accommodation for the workshop. These are scam attempts and should be disregarded. For any questions concerning accommodation, do not hesitate to contact the organizers directly. 

6 August 2024: the workshop program will include a session of short talks ( < 10 minutes) by early career researchers. Information on how to submit a title and brief abstract will be sent to registered and approved participants by the end of September.

Recent progress in theoretical modeling of galaxy clustering has led to new types of data analyses, which are particularly important for constraining extensions of the LCDM cosmological model. However, the landscape of the possible signatures that can be tested using Large Scale Structure observations, including the ongoing DESI and Euclid surveys, remains largely unexplored.

Building on the success of the previous installments

• II at IFPU Trieste in 2023: https://indico.cern.ch/event/1308028/,
• I at CERN in 2022: https://indico.cern.ch/event/1192722/,

the goal of this workshop is to bring together the cosmology and particle theory communities, to discuss current and future opportunities to probe fundamental physics using galaxy clustering.

The workshop will be held at the University of Parma as a fully in-person event. The program will be designed to facilitate interaction, with a limited number of talks accompanied by discussion sessions and ample free time for exchange.

The meeting will start on Monday, November 4, 2024, and end on Friday, November 8.
