Workshop on the Giant Monopole Resonance (GMR)

25 nov. 2020, 14:00 → 26 nov. 2020, 12:15 Europe/Paris

100/-1-A900 - Auditorium Joliot Curie (IJCLab)

In the framework of Working Group 1 (GT1) of the French initiative for Nuclear Physics GDR RESANET (resanet.in2p3.fr) we are organizing a workshop on the measurements of the GMR and their interpretation and importance. We will review the ongoing theoretical and experimental activity on the subject and discuss about future studies.

The workshop will consist in short talks and extended discussion periods. Some of the questions to be addressed are:

• What does one learn about Nuclear Physics from the recent GMR measurements?
• What are the experimental uncertainties on the position of the GMR?
• How do these uncertainties project on the parameters of the equation of state?
• Do soft monopole modes exist and what do they teach us?
• What are the most pertinent nuclei and experimental techniques for future measurements?
