Abstract

We analyze the single transverse-spin asymmetry (SSAs) for inclusive hadron production in the pp collision at RHIC based on the twist-3 mechanism in QCD. As an origin of SSAs, we take into account of all kinds of pole contributions associated with the twist-3 quark-gluon correlation functions in the polarized proton. By the inclusion of the soft-fermion-pole contribution in addition to the soft-gluon-pole contribution, we find SSAs observed at RHIC are better described for all kinds of mesons. P{sub T} dependence of the asymmetry and the comparison with the FNAL data are also presented.

Soft-Fermion-Pole Mechanism to Single Spin Asymmetry in Hadronic Pion Production

Journal Article Koike, Yuji ; Tomita, Tetsuya - AIP Conference Proceedings

Single spin asymmetry (SSA) is a twist-3 observable in the collinear factorization approach. We present a twist-3 single-spin-dependent cross section formula for the pion production in pp-collision, p{sup a}rrow upp->piX, relevant to RHIC experiments. In particular, we calculate the soft-fermion-pole (SFP) contribution to the cross section from the quark-gluon correlation functions. We show that its effect can be as large as the soft-gluon-pole (SGP) contribution owing to the large SFP partonic hard cross section, even though the derivative of the SFP function does not participate in the cross section.

PROCEEDINGS OF RIKEN BNL RESEARCH CENTER WORKSHOP ENTITLED ''SINGLE SPIN ASYMMETRIES'' (VOLUME 75)

Conference YUAN, F ; VOGELSANG, W

Single-transverse spin asymmetries (SSA) in strong interactions have a long history, starting from the 1970s and 1980s when surprisingly large single-transverse spin asymmetries were observed in p+p {yields} {pi}X and pp {yields} {Lambda} + X, where really none were expected. They have again attracted much interest in recent years from both experimental and theoretical sides. In particular, first measurements by the STAR, PHENIX, and BRAHMS collaborations at RHIC have now become available which again reveal large single transverse spin asymmetries for hadron production in polarized proton proton scattering. This extends the SSA observations from the fixed target energy range tomore »« less

Twist-3 quark-gluon correlation contribution to single-transverse spin asymmetry for direct-photon and single-jet productions in pp collision

Journal Article Kanazawa, K. ; Koike, Y. - Physics of Particles and Nuclei

We study the contribution of the collinear twist-3 quark-gluon correlation to the single transversespin asymmetry in direct-photon and single-jet productions in pp collision. At typical RHIC kinematics we find sizable asymmetries in the forward region of the polarized nucleon while they are almost zero in the backward region. We also find the soft-fermion pole contribution is vanishingly small, suggesting the measurement of these asymmetries provides us with an unique opportunity to determine the net soft-gluon pole function.

The transverse nucleon single-spin asymmetry for the semi-inclusive production of photons in lepton-nucleon scattering

Journal Article Albaltan, Weeam S. ; Prokudin, Alexei ; Schlegel, Marc - Physics Letters B

We study the semi-inclusive production of real, high-$$p_T$$, isolated photons in unpolarized and polarized lepton-proton collisions, $$\ell p\to \ell\gamma X$$. In particular we analyze the transverse nucleon single-spin asymmetry within the collinear twist-3 formalism in perturbative QCD to leading order (LO) accuracy. We find that this spin asymmetry is generated by twist-3 dynamical quark-gluon-quark ($qgq$) correlations in the nucleon through the so-called soft-fermion and hard pole contributions. Hence, this process unprecedentedly allows for a point-by-point scan of the support of the dynamical $qgq$ twist-3 matrix elements $$F_{FT}(x,x^\prime)$$ and $$G_{FT}(x,x^\prime)$$ in lepton-nucleon scattering experiments.

Quark-gluon correlation functions relevant to single transverse spin asymmetries

Journal Article Zhongbo, Kang ; Jianwei, Qiu ; C. N. Yang Institute for Theoretical Physics, Stony Brook University, Stony Brook, New York 11794-3840 ; ... - Physical Review. D, Particles Fields

We investigate the relative size of various twist-3 quark-gluon correlation functions relevant to single transverse spin asymmetries (SSAs) in a quark-diquark model of the nucleon. We calculate the quark-gluon correlation function T{sub q,F}(x,x) that is responsible for the gluonic pole contribution to the SSAs, as well as T{sub q,F}(0,x) and T{sub {Delta}q,F}(0,x) responsible for the fermionic pole contributions. We find in both cases of a scalar diquark and an axial-vector diquark that at the first nontrivial order only the T{sub q,F}(x,x) is finite while all other quark-gluon correlation functions vanish. Using the same model, we evaluate quark Sivers function andmore »« less
