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 ...
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 ...
High-energy parton-parton amplitudes from lattice QCD and the stochastic vacuum model
(American Physical SocCollege PkEUA, 1998)
Uncertainties in pion and kaon fragmentation functions
(American Physical Society, 2012-10)
We present a detailed assessment of uncertainties in parton-to-pion and parton-to-kaon fragmentation functions obtained in recent global QCD analyses of single-inclusive hadron production data at next-to-leading order ...
Global Analysis of Nuclear PDFs
(Societa Italiana de Fisica, 2013-10-03)
We present a new global QCD analysis of nuclear parton distribution functions. In addition to the most commonly analyzed data sets for deep inelastic scattering of charged leptons off nuclei and Drell Yan di-lepton production, ...
Coefficient functions and open charm production in deep inelastic scattering
(American Physical SocCollege PkEUA, 1999)
Exclusive processes in electron-ion collisions
(ELSEVIER SCIENCE BV, 2011)
The exclusive processes in electron-ion (eA) interactions are an important tool to investigate the QCD dynamics at high energies as they are in general driven by the gluon content of the target which is strongly subject ...
Parton-to-kaon fragmentation revisited
(American Physical Society, 2017-05)
We revisit the global QCD analysis of parton-to-kaon fragmentation functions at next-to-leading-order accuracy using the latest experimental information on single-inclusive kaon production in electron-positron annihilation, ...
Collective Perspective on Advances in Dyson-Schwinger Equation QCD
(Iop Publishing Ltd, 2012-07-01)
We survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson-Schwinger equations,addressing the following aspects: confinement and dynamical chiral symmetry breaking; the hadron spectrum; ...
Drell-Yan as a probe of small x partons at the LHC
(SPRINGERNEW YORK, 2012)
The predictions of Drell-Yan production of low-mass lepton pairs, at high rapidity at the LHC, are known to depend sensitively on the choice of factorization and renormalization scales. We show how this sensitivity can be ...
