Abstract

We present calculation on the azimuthal spin asymmetries for pion pair production in semi-inclusive deep inelastic scattering (SIDIS) process at both HERMES and COMPASS kinematics, with transversely polarized proton, deuteron, and neutron targets. We calculate the asymmetry by adopting a set of parametrization of the interference fragmentation functions and two different models for the transversity. We find that the result for the proton target is insensitive to the approaches of the transversity but more helpful to understand the interference fragmentation functions. However, for the neutron target, which can be obtained through using deuteron and {sup 3}He targets, we find different predictions for different approaches to the transversity. Thus probing the two pion interference fragmentation from the neutron can provide us more interesting information on the transversity.

Measurement of single-target spin asymmetries in the electroproduction of negative pions in the semi-inclusive deep inelastic reaction n^↑(e,e'π^-)X on a transversely polarized ³He target

Thesis/Dissertation Dutta, Chiranjib

The experiment E06010 measured the target single spin asymmetry (SSA) in the semiinclusive deep inelastic (SIDIS) n^↑(e,e'π^-)X reaction with a transversely polarized ³He target as an e ective neutron target. This is the very rst independent measurement of the neutron SSA, following the measurements at HERMES and COMPASS on the proton and the deuteron. The experiment acquired data in Hall A at Je erson Laboratory with a continuous electron beam of energy 5.9 GeV, probing the valence quark region, with x = 0.13 → 0.41, at Q² = 1.31 → 3.1 GeV². The two contributing mechanisms to the measured asymmetry,more »« less

Six “beyond Collins and Sivers” transverse spin asymmetries at COMPASS

Journal Article Parsamyan, B. - Physics of Particles and Nuclei

COMPASS is a fixed-target high energy physics experiment at the SPS at CERN [1]. One of the important objectives of the experiment is the exploration of the transverse spin structure of the nucleon via spin dependent azimuthal asymmetries in single-hadron production in deep inelastic scattering of polarized leptons off transversely polarized target. For this purpose a series of measurements were made in COMPASS, using 160 GeV/c longitudinally polarized muon beam and transversely polarized {sup 6}LiD (in 2002, 2003 and 2004) and NH{sub 3} (in 2007 and 2010) targets. Till now main attention was focused on Collins and Sivers asymmetries andmore »« less

Extraction of quark transversity distribution and Collins fragmentation functions with QCD evolution

Journal Article Kang, Zhong-Bo; Prokudin, Alexei; Sun, Peng; ... - Physical Review D

In this paper, we study the transverse momentum dependent (TMD) evolution of the Collins azimuthal asymmetries in e⁺e^- annihilations and semi-inclusive hadron production in deep inelastic scattering (SIDIS) processes. All the relevant coefficients are calculated up to the next-to-leading logarithmic (NLL) order accuracy. By applying the TMD evolution at the approximate NLL order in the Collins- Soper-Sterman (CSS) formalism, we extract transversity distributions for u and d quarks and Collins fragmentation functions from current experimental data by a global analysis of the Collins asymmetries in back-to-back di-hadron productions in e⁺e^- annihilations measured by BELLE and BABAR Collaborations and SIDIS datamore »« less

Single target-spin asymmetry in semi-inclusive deep inelastic scattering on a transversely polarized nucleon target

Journal Article Yang, Huang; Jun, She; Boqiang, Ma - Physical Review. D, Particles Fields

We use a new set of Collins functions to update a previous prediction on the azimuthal asymmetries of pion production in a semi-inclusive deep-inelastic scattering process on a transversely polarized nucleon target. We find that the calculated results can give a good explanation to the HERMES experiment with the new parametrization, and this can enrich our knowledge of the fragmentation process. Furthermore, with two different approaches of distribution and fragmentation functions, we present a prediction on the azimuthal asymmetries of pion and kaon production at the kinematics region of the experiments E06010 and E06011 planned at Jefferson Lab.

The Halls B and C semi-inclusive deep inelastic scattering program towards the transverse momentum dependence of valence quarks

Conference Ent, Rolf

Inclusive and semi-inclusive deep inelastic scattering (DIS and SIDIS) are important tools for understanding the structure of nucleons and nuclei. Spin asymmetries in polarized SIDIS are directly related to transverse momentum dependent parton distributions (TMDs) and fragmentation functions. The usual collinear parton distribution functions depend on the fraction of hadron momentum carried by the parton, x, and the space-time resolution scale, Q2. The TMDs, which depend also on the intrinsic transverse momentum of the parton, kT, provide a three-dimensional partonic picture of the nucleon in momentum space. These TMDs have not yet been studied in detail. The 12 GeV eramore »« less
