Title: Single-spin asymmetries at two loops

Abstract

We find a novel mechanism for generating transverse single-spin asymmetry (SSA) in semi-inclusive deep inelastic scattering, distinct from the known ones which involve the Sivers and Collins functions, or their collinear twist-three counterparts. It is demonstrated that a phase needed for SSA can be produced purely within a parton-level cross section starting at two loops. We identify the complete set of two-loop diagrams for SSA, and discuss their gauge invariance and collinear factorization which features the gT distribution function. In the kT factorization framework, many more sources for SSA exist, and contributions from all possible two-parton transverse-momentum-dependent parton distribution functions are presented up to two loops and twist three.

Azimuthal asymmetries for hadron distributions inside a jet in hadronic collisions

Journal Article D'Alesio, Umberto ; Pisano, Cristian ; Istituto Nazionale di Fisica Nucleare, Sezione di Cagliari, C. P. 170, I-09042 Monserrato ; ... - Physical Review. D, Particles Fields

Using a generalized parton model approach including spin and intrinsic parton motion effects, and assuming the validity of factorization for large-p{sub T} jet production in hadronic collisions, we study the azimuthal distribution around the jet axis of leading unpolarized or (pseudo)scalar hadrons, namely pions, produced in the jet fragmentation process. We identify the observable leading-twist azimuthal asymmetries for the unpolarized and single-polarized case related to quark and gluon-originated jets. We account for all physically allowed combinations of the transverse momentum-dependent (TMD) parton distribution and fragmentation functions, with special attention to the Sivers, Boer-Mulders, and transversity quark distributions, and to themore »« less

Measurement of Single Spin Asymmetry in ³He↑(e, e'K ^±)X from a Transversely Polarized ³He Target

Thesis/Dissertation Zhao, Yuxiang

Spin-dependent observables are a powerful tool to probe the internal structure of the nucleon and to study the dynamics of the strong interaction. Experimental study of the nucleon spin structure has provided us with many exciting and often surprising results. The so-called "spin crisis" in the 1980s revealed the limitation of naive quark-parton models and led to a worldwide effort to study the nucleon spin structure. However, this effort has been focused mainly on the nucleon's longitudinal spin structure. Recently, when the pioneer work revealed the significant role that transverse spin plays in understanding the full structure of the nucleonmore »« less

Single spin asymmetries in lp{yields}hX processes: A test of factorization

Journal Article Anselmino, M. ; Boglione, M. ; Prokudin, A. ; ... - Physical Review. D, Particles Fields

Predictions for the transverse single spin asymmetry (SSA), A{sub N}, are given for the inclusive processes lp{sup {up_arrow}{yields}h}X and lp{sup {up_arrow}{yields}j}et+X, which could be measured in operating or future experiments. These estimates are based on the Sivers distributions and the Collins fragmentation functions which fit the azimuthal asymmetries measured in semi-inclusive deep inelastic scattering (SIDIS) processes (lp{sup {up_arrow}{yields}l'}hX). The factorization in terms of transverse momentum dependent distribution and fragmentation functions (TMD factorization)--which supplies the theoretical framework in which SIDIS azimuthal asymmetries are analyzed--is assumed to hold also for the lp{yields}hX inclusive process at large P{sub T}.

Novel Spin Effects in QCD

Technical Report Brodsky, S

Measurements from HERMES, SMC, and Jlab show a significant single-spin asymmetry in semi-inclusive pion leptoproduction {gamma}*(q)p {yields} {pi}X when the proton is polarized normal to the photon-to-pion production plane. Hwang, Schmidt, and I [1] have shown that final-state interactions from gluon exchange between the outgoing quark and the target spectator system lead to such single-spin asymmetries at leading twist in perturbative QCD; i.e., the rescattering corrections are not power-law suppressed at large photon virtuality Q{sup 2} at fixed x{sub bj}. The existence of such single-spin asymmetries (the Sivers effect) requires a phase difference between two amplitudes coupling the proton targetmore »« less
