CONCLUSION

  • ALICE is collecting data and producing papers. Computing and Upgrade?

  • The first experimental campaign with the AGATA demonstrator has started at LNL. The realization of ¼ of solid angle is in progress. Nuclei at extremes are being investigated.

  • Esperiments engaged in upgrades

  • such as JLAB and LUNA are progressing.

  • Several relevant results are obtained with the analysis of experiments under way. They are important to guide the future programs.

  • We count on the activity at JLAB

  • for which also in the future (as in the past) we expect outstanding results !
