The g2 Structure Function: An Experimental Overview
K. Slifer
We will discuss recent results for the spin structure functions, with an emphasis on g2 . High precision g2 data allows for tests of the Burkhardt-Cottingham sum rule, and is neede…
Recent STAR Results from Charged Pion Production in Polarized pp Collisions at at RHIC
Adam Kocoloski
The STAR experiment at RHIC measures the longitudinal double-spin asymmetry for a variety of final states in collisions of longitudinally polarized protons to constrain th…
Accessing the Sign and Magnitude of G via high , in Polarized p+p Collisions at PHENIX
Astrid Morreale
The double-helicity asymmetries () of and production in polarized proton proton collisions are specially interesting probes of the gluon's polarization. Rel…
A Review of Nucleon Spin Calculations in Lattice QCD
Huey-Wen Lin
We review recent progress on lattice calculations of nucleon spin structure, including the parton distribution functions, form factors, generalization parton distributions, and rec…
within a Handbag Picture -- Cross Section and Spin Observables
A. T. Goritschnig, P. Kroll, W. Schweiger
We study the process within the generalized parton picture. Our starting point is the double handbag diagram which factorizes into soft generalized parto…
Chiral Odd Generalized Parton Distributions in Position Space
A. Mukherjee, D. Chakrabarti, R. Manohar
We report on a calculation of the chiral odd generalized parton distributions (GPDs) for non-zero skewness in transverse and longitudinal position spaces by taking Fourier tran…
Target mass corrections and beyond
Alberto Accardi
I examine the uncertainty of perturbative QCD factorization for (un)polarized hadron structure functions in deep inelastic scattering at a large value of the Bjorken variable xB. T…
Parton Distributions in the Impact Parameter Space
Matthias Burkardt
Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when the target and/or quark is…
Future Investigations of the Flavor Dependence of Sea Quark Helicities at STAR
J. Sowinski
The flavor dependence of polarized and unpolarized quark distributions in the nucleon can lead to insights into the formation of the sea. Drell-Yan measurements have pointed to fla…
Electron Spin Precession at CEBAF
D. W. Higinbotham
The nuclear physics experiments at the Thomas Jefferson National Accelerator Facility often require longitudinally polarized electrons to be simultaneously delivered to three exper…
Constraints on Delta G through Longitudinal Double Spin Asymmetry Measurements of Inclusive Jet Production in Polarized p+p Collisions at 200 GeV
M. Sarsour
We report measurements of the longitudinal double spin asymmetry for inclusive jet production using polarized p+p collisions at sqrt{s} = 200 GeV at RHIC. Results from the 2005 and…
Spin-dependent Forward Particle Correlations in p+p Collisions at GeV
Nikola Poljak
The STAR collaboration has reported precision measurements of the transverse single spin asymmetries for the production of the mesons from polarized proton collisions at $\sq…
pi^0 Transverse Single-Spin Asymmetries at eta=4.1 in p+p Collisions at sqrt{s}=200 GeV
J. L. Drachenberg
Large transverse single-spin asymmetries, A_{N}, have been observed in forward hadron production at RHIC. STAR has reported precision measurements of the x_{F}-p_{T} dependence of…
Status of Longitudinal Polarized Parton Densities and Higher Twist
Elliot Leader, Alexander V. Sidorov, Dimiter B. Stamenov
The present status of the longitudinal polarized parton densities (PDFs) and the contribution of their first moments to the nucleon spin is discussed. Special attention is paid to…
Spin beyond Standard Model: Theory
Jens Erler
I use spin as a guide through the labyrinth of possibilities and ideas that go beyond the established understanding of the fundamental interactions.
