2. What is NuSTAR ? Basic research in Nuclear STructure Nuclear Astrophysics Nuclear Reactions with beams of short-lived nuclei at energies 0 – 1.5 GeV/u @ FAIR International collaboration for physics with radioactive ion beams at FAIR International collaboration (established in 2003) chair: W.Gelletly, Univ. of Surrey, UK members: > 700 nuclear scientists > 120 institutions > 25 countries purpose: superstructure of 9 experimental collaborations at FAIR including nuclear theory HIC for FAIR aims at an exploitation of the hightech opportunities at the FAIR accelerator complex. The HIC will guarantee a dominant role in selected NuSTAR experiments and theory for Hessian universities, its students, and society. Norbert Pietralla

3. Motivation for NuSTAR Norbert Pietralla

4. Motivation for NuSTAR • What are the limits of nuclear existence ? • How does the nuclear force depend on a variation of the proton-to-neutron ratio ? • How do collective nuclear phenomena emerge from nucleons and nuclear force ? • How are complex nuclei formed from the underlying constituents and QCD ? • What nuclei are relevant for cosmic processes and what are their properties ? Norbert Pietralla

5. HIC for FAIR project areas • Monte Carlo methods • Coupled partial-differential equations • QCD-phenomenology • Detector design, Optimization and R&D • Pattern recognition and Trigger concepts • Large volume data analysis • Accelerator optimization and R&D HIC for FAIR concentrates on strategic NuSTAR activities that complement the expertise of HIC‘s partner institutions.
