The Nuclear Physics and Dense Matter Equation of State Workshop was held at the Facility for Rare Isotope Beams (FRIB), Michigan State University, from December 8-12, 2025. Organized under the CNRS-MSU International Research Laboratory on Nuclear Physics and Nuclear Astrophysics (IRL-NPA), this event aimed to strengthen collaboration between French CNRS researchers and FRIB scientists.

The workshop focused on a central question in modern physics: What is the pressure of dense matter at twice saturation density? This topic is essential for understanding neutron stars and the equation of state of dense matter. By gathering experts in nuclear physics, astrophysics, and gravitational wave research, the event compared predictions from nuclear physics constraints with astrophysical observations, such as those from neutron star mergers and pulsars.

Through presentations and discussions, participants explored the origins of uncertainties in these predictions and assessed whether different approaches overlapped or diverged. The goal was to foster mutual understanding and identify areas for further research, ultimately advancing our knowledge of neutron stars and dense matter.

The workshop featured talks from leading scientists, and provided a unique platform for researchers to connect and collaborate across disciplines.
