TheoS: Theoretical Support for Nuclear Facilities in Europe 
WP Leader: Denis Lacroix
Deputy: Antonio Moro
The main objective of TheoS is to provide a strong and reliable theoretical support to the experiments that will be performed at the TAs of ENSAR2, including the ESFRI projects FAIR, SPIRAL2 and ELI-NP. This goal will be reached by improving our knowledge of nuclei both starting from first principles and by improving existing phenomenological models in nuclear structure and reactions. Links with other areas of physics, like hadron physics and astrophysics, will be emphasised within TheoS. In addition, this JRA will build a community to coordinate the research in nuclear theory within Europe.
