EMMI Workshop and International Workshop XLIX on Gross Properties of Nuclei and Nuclear Excitations

Scope of the meeting

The workshop addresses the following main topics and goals:

  • What are the limits of EFT for nuclei and for matter? What should be the priority developments and improvements for EFTs, including the exploration of alternative power counting schemes?
  • What are systems where more effective EFTs, such as pionless or halo EFT, are particularly promising? What are priorities for improving nuclear energy density functionals in the spirit of EFT?
  • What are the priorities for developments and applications in uncertainty quantification? What are new opportunities for nuclear structure from emerging technologies?
  • What should be EFT and many-body priorities in nuclear structure research in light of the advent of new experimental facilities for the study of exotic nuclei?

Workshop format

The program will consist of invited talks and selected contributions. Sessions will take place from 9:00am to 12:00am and from 4:30pm to 6:30pm.

The workshop takes place at the Darmstädter Haus.
