Towards a global analysis of polarized parton distributions
M. Stratmann, W. Vogelsang
We present a technique for implementing in a fast way, and without any approximations, higher-order calculations of partonic cross sections into global analyses of parton distribut…
Probing the parton densities of polarized photons at a linear e^+e^- collider
M. Stratmann
The present theoretical status of spin-dependent parton densities Delta f^γ(x,Q^2) of circularly polarized photons is briefly reviewed. It is then demonstrated that measurements of…
Next-to-Leading Order QCD Corrections to Charged Current Charm Production and the Unpolarized and Polarized Strange Sea at HERA
S. Kretzer, M. Stratmann
Charged current charm and D meson production is studied in detail as a means of determining the unpolarized and polarized strange sea densities at HERA. All analyses are performed…
Transverse Double-Spin Asymmetries for Muon Pair Production in pp-Collisions
O. Martin, A. Schafer, M. Stratmann +1
We calculate the rapidity dependence of the transverse double-spin asymmetry for the Drell-Yan process to next-to-leading order in the strong coupling. Input transversity distribut…
Mesonic Parton Densities Derived From Constituent Quark Model Constraints
M. Gluck, E. Reya, M. Stratmann
Using constituent quark model constraints we calculate the gluon and sea content of pions solely in terms of their valence density and the known sea and gluon densities of the nucl…
Next-to-Leading Order Evolution of Polarized Fragmentation Functions
M. Stratmann
We present a brief description of the determination of the two-loop spin-dependent time-like splitting functions relevant for the NLO evolution of polarized fragmentation functions…
