1. UK Research in Nuclear Physics P J Nolan University of Liverpool

2. Nuclear Physics has been funded by EPSRC funding was on a project by project basis Nuclear Physics is now funded by STFC funding decisions are yet to be made, but are likely to be more strategic

3. Nuclear Physics research is carried out in 10 UK institutions there are ~60 academic staff past support has resulted in: ~45 PDRAs ~100 Research students ~20 Expert support staff ~20 Technical support staff

4. Nuclear Physics experimental research is carried out at international facilities All experimental work is in international collaborations with UK physicists leading individual physics programmes There is a programme of theoretical research based at Manchester and Surrey, also with strong international collaborations

5. Nuclear Physics Research in the UK is in FOUR main areas: Nuclear Structure Nuclear Astrophysics Hadron Physics The Phases of Strongly Interacting Matter

6. Nuclear Structure Some key questions: What are the limits of nuclear existence? What is the heaviest element we can make? How does nuclear structure evolve at the highest angular momentum, just before the fission limit? Are there new forms of nuclear matter in very loosely bound nuclear systems? How does the ordering of quantum states, with all of its consequent implications for nuclear structure and reactions, alter in highly dilute or neutron-rich matter? Do symmetries seen in near-stable nuclei also appear far from stability and do we observe new symmetries? etc.

7. Nuclear Astrophysics Some key questions: How are the elements and isotopes found in the Universe formed? Where are the sites of the r-process(es) of nucleosynthesis? What are the reaction rates of key exotic nuclei in the hot CNO cycles and rp processes? What are the ultra low energy nuclear astrophysical reaction rates at the Gamow peak in stellar burning scenarios? What is the nuclear equation of state for neutron stars? How do density induced pyconuclear fusion reactions take place in the crusts of neutron stars? etc.

8. Hadron Physics Some key questions: Why are there no free quarks in nature? What is the exact mechanism for the confinement of quarks in hadrons What is the origin of the masses of the hadrons? What is the origin of the spin of the nucleons? What is the connection between parton degrees of freedom and the low energy structure of hadrons? What is the excitation spectrum of the nucleon? Do new forms of hadrons such as exotic hybrid mesons (qqg) or glueballs (ggg) exist, as predicted by lattice-QCD? etc.

9. The Phases of Strongly Interacting Matter Some key questions: Is there evidence of gluon saturation in nuclei in high energy nucleus-nucleus collisions? Can we determine the bulk properties of the quark-gluon plasma and with what accuracy? How does the collective behaviour of hot, quark-deconfined matter challenge our understanding of QCD derived from low energy hadronic physics? Are there indications of the deconfinement phase transition at high baryon density? Can we locate the critical point on the QCD phase diagram? Are exotic states of matter such as strange-particle condensates formed in such collisions? etc.

10. Nuclear Physics research requires a range of facilities as: Different nuclear species have to be made in optimum conditions Radioactive beam facilities Stable beam facilities The radiation emitted has to be detected in spectrometers designed for the purpose, examples include AGATA, PANDA, etc. Each experiment has to be optimised depending on its goals
