Title: Collins azimuthal asymmetries of hadron production inside jets

Abstract

We investigate the Collins azimuthal asymmetry of hadrons produced inside jets in transversely polarized proton–proton collisions. Recently, the quark transversity distributions and the Collins fragmentation functions have been extracted within global analyses from data of the processes semi-inclusive deep inelastic scattering and electron–positron annihilation. We calculate the Collins azimuthal asymmetry for charged pions inside jets using these extractions for RHIC kinematics at center-of-mass energies of 200 and 500 GeV. We compare our results with recent data from the STAR Collaboration at RHIC and find good agreement, which confirms the universality of the Collins fragmentation functions. In addition, we further explore the impact of transverse momentum dependent evolution effects.

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

In this paper we briefly review the transverse momentum dependent generalized parton model and its application to the study of azimuthal asymmetries in the distribution of leading hadrons (mainly pions) inside large transverse momentum jets inclusively produced in polarized proton-proton collisions. We put particular emphasis on the phenomenological interest of these observables, in combination with similar asymmetries measured in semi-inclusive deeply inelastic scattering, Drell-Yan processes and e{sup +} e{sup −} collisions, for the study of the universality properties of the transverse momentum dependent parton distribution and fragmentation functions. We present results for RHIC kinematics at center-of-mass energies √s = 200more »« less

Collins asymmetry at hadron colliders

Journal Article Feng, Yuan ; RIKEN BNL Research Center, Brookhaven National Laboratory, Building 510A, Upton, New York 11973 - Physical Review. D, Particles Fields

We study the Collins effect in the azimuthal asymmetric distribution of hadrons inside a high energy jet in the single-transverse polarized proton-proton scattering. From the detailed analysis of one-gluon and two-gluon exchange diagrams contributions in a particular model, the Collins function is found the same as that in the semi-inclusive deep inelastic scattering and e{sup +}e{sup -} annihilations. The eikonal propagators in these diagrams do not contribute to the phase needed for the Collins-type single-spin asymmetry, and the universality is derived as a result of the Ward identity. We argue that this conclusion depends on the momentum flow of themore »« less

ECCE sensitivity studies for single hadron transverse single spin asymmetry measurements

Journal Article Seidl, R. ; Vladimirov, A. ; Pitonyak, D. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

We performed feasibility studies for various single transverse spin measurements that are related to the Sivers effect, transversity and the tensor charge, and the Collins fragmentation function. The processes studied include semi-inclusive deep inelastic scattering (SIDIS) where single hadrons (pions and kaons) were detected in addition to the scattered DIS lepton. The data were obtained in pythia6 and geant4 simulated e+p collisions at 18 GeV on 275 GeV, 18 on 100, 10 on 100, and 5 on 41 that use the ECCE detector configuration. Typical DIS kinematics were selected, most notably Q²>1 GeV², and cover the x range from 10^-4more »« less

Role of transverse momentum dependence of unpolarized parton distribution and fragmentation functions in the analysis of azimuthal spin asymmetries

Journal Article Anselmino, M. ; Boglione, M. ; D’Alesio, U. ; ... - Physical Review D

Information on the Sivers distribution and the Collins fragmentation functions and their transverse momentum dependence is mainly based on fitting single-spin asymmetry data from semi-inclusive deep inelastic scattering (SIDIS). Independent information on the Sivers distribution and the Collins fragmentation can be obtained from the Drell-Yan and e⁺e^- annihilation processes, respectively. In the SIDIS case, the transverse momentum of the final observed hadron, which is the quantity measured, is generated both by the average transverse momentum in the distribution and by that in the fragmentation functions. As a consequence, these are strongly correlated, and a separate extraction is made difficult. Inmore »« less
