Particle physics Nuclear physics
Transition from the perturbative to the non-perturbative regime of Quantum-Chromodynamics (QCD) Particle physics Nuclear physics perturbative: QCD: aS << 1 non-perturbative: QCD: aS 1 q Gluon (g) Hadrons: Baryons, Mesons Models, Lattice QCD Quarks, Gluons One-Gluon Exchange

Proton Charge and Magnetization The importance of the anti-quark sea
Baryon Structure Proton Charge and Magnetization The importance of the anti-quark sea LA-LP-98-56 Lots of issues – not general agreement on what path is best The distribution of charge and magnetization are different There are more down-anti-down quark pairs than up-anti-up quarks pairs in the sea of the proton.

Advantages of 120 GeV Main Injector
The Nature of the Sea The (very successful) past: Fermilab E866/NuSea Data in 1H, 2H, and nuclear targets 800 GeV proton beam The future: Fermilab E906 Data in 1H, 2H, and nuclear targets 120 GeV proton Beam Fixed Target Beam lines Tevatron 800 GeV Cross section scales as 1/s 7 x that of 800 GeV beam Backgrounds, primarily from J/ decays scale as s 7 x Luminosity for same detector rate as 800 GeV beam 50 x statistics!!

The Nuclear Landscape The Nuclear Physics of RI Beams rare isotopes
as a beam stable particles as target The nature of the nuclear force a strong manifestation of its tensor nature is in changes of shell structure possible changes in effective interactions and correlations near the limits of stability exploration of limits: driplines, super-heavy elements, fission barriers …. The origin of (simple) patterns in nuclei origin of collectivity new collective modes, shapes and symmetries nature of halos and skins, their influence on symmetries decoupling of neutron degrees of freedom The Nuclear Landscape

The Phases of QCD Did the properties of the Quark Gluon Plasma and the quark-gluon to hadron phase transition affect the evolution of the universe? Does the nature of the plasma and the quark-hadron transition give us new insight into QCD and confinement? Do states of de-confined quark and gluon matter exist now, i.e. at the core of neutron stars?
