Global analysis of nuclear parton distributions
(American Physical Society, 2012-04)
We present a new global QCD analysis of nuclear parton distribution functions and their uncertainties. In addition to the most commonly analyzed data sets for the deep-inelastic scattering of charged leptons off nuclei and ...
Could saturation effects be visible in a future electron-ion collider?
(ELSEVIER SCIENCE BV, 2009)
We expect to observe parton saturation in a future electron-ion collider. In this Letter we discuss this expectation in more detail considering two different models which are in good agreement with the existing experimental ...
Nonforward parton distributions of the pion within an effective single instanton approximation
We develop a relativistic quark model for pion structure, which incorporates the nontrivial structure of the vacuum of quantum chromodynamics as modelled by instantons. Pions are bound states of quarks and the strong ...
QCD spin physics: Partonic spin structure of the nucleon
(Elsevier Science, 2012-04)
We discuss some recent developments concerning the nucleon's helicity parton distribution functions: new preliminary data from jet production at RHIC suggest for the first time a non-vanishing polarization of gluons in the ...
