Delta G from Compass

open access: yes, 2006
Measurements of the gluon polarization $\frac{\Delta G}{G}$ via the open charm channel and based on the helicity asymmetry of large transverse-momentum hadrons in the final state are presented.

Global analysis of AAC for determining polarized parton distribution functions

open access: yes, 2006
We report global analysis results for polarized parton distribution functions in the nucleon. The optimum distributions are determined by using spin asymmetry data on polarized lepton scattering on proton, neutron, and deuteron.

Asymptotic behaviour of the Einstein-Vlasov system with a positive cosmological constant

open access: yes, 2003
We study locally spatially homogeneous solutions of the Einstein-Vlasov system with a positive cosmological constant. First the global existence of solutions of this system and the casual geodesic completeness are shown.

Quark-Hadron Duality in Neutron (3He) Spin Structure

open access: yes, 2008
We present experimental results of the first high-precision test of quark-hadron duality in the spin-structure function g_1 of the neutron and $^3$He using a polarized 3He target in the four-momentum-transfer-squared range from 0.7 to 4.0 (GeV/c)^2 ...

Recent STAR results in high-energy polarized proton-proton collisions at RHIC

open access: yes, 2010
The STAR experiment at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory is carrying out a spin physics program in high-energy polarized $\vec{p}+\vec{p}$ collisions at $\sqrt{s}=200-500\,$GeV to gain a deeper insight into the spin ...
