Low-energy nuclear theory: From few nucleons to the stars

13 nov. 2025, 09:00 → 14 nov. 2025, 18:00 Europe/Paris

100/0-MXX - Salle des Conseils (IJCLab)

     

🧪 Workshop Overview

 

This two-day workshop will focus on the role of low-energy nuclear theory in advancing our understanding of systems ranging from a few nucleons in the laboratory to large-scale astrophysical processes.

The primary goal of this event is to foster new collaborations and research projects among group members and their extended network of collaborators. Discussions will span a broad spectrum of topics—from nuclear density functional theory to effective field theory methods—with an emphasis on building bridges across approaches and applications.

 

 

We are especially grateful to the Graduate School of Physics of the Paris-Saclay University for sponsoring this event within the physics of the 2 inifinities (P2I) program.
