Longitudinal Gluon Polarization in RHIC Double-Spin Asymmetries
B. Jager, S. Kretzer, M. Stratmann +1
The longitudinally polarized gluon density is probed sensitively in hard collisions of polarized protons under the condition that the dominant dynamics are perturbative and of lead…

Determining the Spin Structure of the Photon at Future Colliders
M. Stratmann
It is demonstrated that measurements of the spin asymmetry for di-jet production at future polarized colliders appear to be particularly suited for a first determination of the so…
Polarized Parton Densities and Processes
M. Stratmann
The main goals of `spin physics' are recalled, and some theoretical and phenomenological aspects of longitudinally polarized deep inelastic scattering and other hard processes are…
Towards the Parton Densities of Polarized Photons at HERA
M. Stratmann, W. Vogelsang
Di-jet photoproduction in polarized ep collisions at HERA is studied as a possible tool to determine the parton content of circularly polarized photons. The concept of the `effecti…
The Parton Content of Virtual Photons
M. Stratmann
The QCD treatment of the parton structure of virtual photons is briefly recalled, and possible limitations and open questions are pointed out. Various models for these densities ar…
