QCD Spin Physics: Partonic Spin Structure of the Nucleon
نویسندگان
چکیده
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 nucleon. SIDIS measurements at COMPASS provide better constraints on the strange and light sea quark helicity distributions. Single-longitudinal spin asymmetries in W -boson production have been observed at RHIC and will ultimately give new insights into the light quark and anti-quark helicity structure of the nucleon.

Partonic Structure of the Nucleon in Qcd and Nuclear Physics: New Developments from Old Ideas
The nucleon is an ideal laboratory to solve QCD in the nonperturbative regime. There are several experimental observations that still lack a rigorous interpretation; they involve the nucleon as a (polarized) target as well as a beam (in collisions and Drell-Yan processes). These data look like big azimuthal and spin asymmetries, related to the transverse polarization and momentum of the nucleon...
متن کاملA New Approach for Single Transverse-Spin Asymmetries from Twist-3 Soft-Gluon Mechanism
A dominant QCD mechanism for the single transverse-spin asymmetry in hard processes is induced by the twist-3 quark-gluon correlations inside nucleon, combined with the soft-gluonic poles to produce the interfering phase for the associated partonic hard scattering. It is shown that the corresponding interfering amplitude can be calculated entirely in terms of the partonic Born cross section whi...
متن کاملSpin-spin asymmetries in large transverse momentum Higgs-boson production.
We examine the spin-dependence of standard model Higgs boson production at large transverse momentum via the processes gg → gH0, qg → qH0, and qq → gH0. The partonic level spin-spin asymmetries (âLL) for these processes are large at SSC/LHC energies. The prospects for probing the spin-dependence of the standard model of particle physics at collider and supercollider energies have recently recei...

The generation of the single spin asymmetries by the twist 3 effects in QCD is discussed. While the short-distance subprocesses is calculable in the Born approximation, some properties of large distance partonic correlations may be extracted by means of sum rules relating them to the DIS spin structure function g 2. The simple model for twist 3 part of the latter is proposed. The numerical anal...
متن کاملProgress in hadron structure physics on the lattice∗
This is a review of progress in hadron structure physics from lattice QCD. Recent results on the structure of the nucleon and the pion in terms of (transition) form factors, moments of distribution amplitudes and (generalized) parton distribution functions are presented. These observables allow us to investigate a number of fundamental physics questions related to e.g. the distribution of charg...
