Bueltmann Abstract

First results from elastic scattering of polarized protons at a cms energy of 200 GeV at the Relativistic Heavy Ion Collider (RHIC) at BNL will be shown. An overview of the RHIC complex with respect to the polarized proton programme, including polarimetry, will be given and the goals of the spin programme be presented. The focus will be on the elastic scattering experiment pp2pp, studying the spin (in-)dependent contributions to the elastic scattering amplitude.

Stankus Abstract

Anomalies in baryon production recently observed in heavy-ion collisions at RHIC have generated new interest in mechanisms for baryon transport. The baryon junction mechanism is reviewed, and methods for verifying the mechanism are discussed. Results of an elementary investigation are presented.

Kreisel Abstract

An extended study of exclusive vector meson production in ep interactions has been performed by the H1 and the ZEUS collaborations at the HERA collider. Recent measurements are reported and discussed within the framework of pQCD models and Regge phenomenology.

Vitev Abstract

We calculate and resum a perturbative expansion of nuclear enhanced power corrections in the quantity (xi^2/Q^2)(A^(1/3)-1) to the structure functions measured in deeply inelastic scattering of leptons on a nuclear target. Our results for the Bjorken x-, Q^2- and A-dependence of nuclear shadowing in F_2^A(x,Q^2) and the nuclear modifications to F_L^A(x,Q^2), calculated in terms of the QCD factorization approach, are consistent with existing data for xi^2=0.09-0.12~GeV^2. We also discuss the impact of our results on the extraction of nuclear parton distribution functions. Less shadowing and correspondingly less antishadowing than currently anticipated may provide important constraints on the interpretation of the d+A and Au+Au data from RHIC. Further theoretical investigation of nuclear enhanced high twist corrections for different observables and future measurements at HERA, RHIC, EIC and LHC are expected to play a critical role in disentangling the process dependent and process independent parts of the strong interaction dynamics at small x.

Lohmann Abstract

An overview will be given on the physics potential of a linear e+e- collider in the energy range up to one TeV. The expectations to explore electroweak symmetry breaking, supersymmetry and for precision measurements are discussed. The status of TESLA and the R&D for a detector are surveyed.

Hafemeister Abstract

The historic ups and downs on the basic bargain of the Nuclear Non-proliferation Treaty will be briefly discussed The Russian stockpile of plutonium/HEU will be estimated from "first principles." Control for the Russian materials will be described in terms of the wide ranging Cooperative Threat Reduction Initiative. The purchase of 500 tonnes of Russian HEU will be briefly analyzed, and projected to other possibilities. The attribute and template approaches to monitor warheads will be described. The guiding criteria for adoption of these technologies will be considered against the standard of effective verification. The global stockpile of plutonium will be estimated from "first principles." The difference between reactor grade Pu and weapon grade Pu will be briefly analyzed. The economics of the plutonium economy will be briefly analyzed in terms of capital costs, the price of uranium and the growth of nuclear power. The shift of the threat from Pu to HEU will be commented on, as well as the link to the Comprehensive Test Ban Treaty.

Ramsey-Musolf Abstract

Supersymmetry (SUSY) is a leading scenario for physics beyond the Standard Model. I discuss what low-energy precision electroweak measurements in nuclear, particle, and atomic physics are teaching us about SUSY and how this information complements what may be learned from collider experiments. I also address some issues pertaining to the theoretical interpretation of low-energy precision measurements.
