Abstract

Transverse momentum dependent parton distributions (TMDs) are an important class of functions required to understand the 3D structure of hadrons in terms of their underlying partons. One of the least known TMDs in terms of a global QCD analysis is the worm-gear TMD_g1t. It carries the probabilistic interpretation of finding longitudinally polarized quarks inside transversely polarized hadrons. In this proceedings, we present the first-ever global QCD analysis of the semi-inclusive DIS $$A^ {cos(φ_h-φ_S)}_{LT}$$ data using Monte Carlo techniques to extract the worm-gear TMD_g1T. The relevant data are available from COMPASS, HERMES and JLab. We compare our results for _g1T with different theoretical approaches, including the large-N_c approximation, the Wandzura Wilczek-type approximation, and lattice QCD.

First Global Extraction of the Worm-gear TMD g₁_T

Journal Article Bhattacharya, Shohini ; Kang, Zhong-Bo ; Metz, Andreas ; ... - JPS Conference Proceedings

In these proceedings, we report on the first simultaneous extraction of the worm-gear function g₁_T, one of the eight leading-twist TMDs. The study analyzes COMPASS, HERMES and JLab semi-inclusive deep-inelastic scattering data using Monte Carlotechniques. We also provide a comparison of g₁_T obtained from this experimental data with a large N_c analysis, the Wandzura–Wilczek-type approximation, and lattice QCD.

First global QCD analysis of the TMD $g_{1 T}$ from semi-inclusive DIS data

Journal Article Bhattacharya, Shohini ; Kang, Zhong-Bo ; Metz, Andreas ; ... - Physical Review D

The worm-gear transverse momentum dependent (TMD) function g_1T is one of the eight leading-twist TMDs and has the probabilistic interpretation of finding a longitudinally polarized quark inside a transversely polarized hadron. In this work, we present the first simultaneous extraction of g_1T from all the available experimental measurements. The study involves the analysis of COMPASS, HERMES, and Jefferson Lab data on semi-inclusive deep-inelastic scattering using Monte Carlo techniques. We also compare g_1T obtained from this experimental data with different theoretical approaches, such as the large-N_c approximation, the Wandzura-Wilczek-type approximation, and lattice QCD.

Experimental results on TMDs

Journal Article Avakian, H. ; Bressan, A. ; Contalbrigo, M. - European Physical Journal. A

QCD factorisation for semi-inclusive deep inelastic scattering (DIS) at low transverse momentum in the current-fragmentation region has been established recently, providing a rigorous basis to study the transverse-momentum-dependent (TMD) distribution and fragmentation functions of partons from semi-inclusive DIS data using different spin-dependent and spin-independent observables. The main focus of the experiments were the measurements of various single- and double-spin asymmetries in hadron electro-production ( ep↑ → ehX with unpolarised, longitudinally and transversely polarised targets. The joint use of a longitudinally polarised beam and longitudinally and transversely polarised targets allowed to measure double-spin asymmetries related to leading-twist distribution functions describing themore »« less

TMDs and PVDIS: JLab 6 GeV results and 12 GeV Plan

Conference Chen, Jian-Ping

The talk shows recent and new results with a transversely polarized 3He(n) to explore TMDs with 6 GeV JLab, including Collins/Sivers/Worm-gear asymmetries on pions and Kaons, inclusive hadron and electron SSA. Then presents JLab-12GeV plan for TMD study - high precision Multi-d mapping, with focusing on the SoLID program on TMDs. The talk also shows new results of PVDIS with 6 GeV JLab, which were just published in Nature. Then discussed the 12 GeV plan for PVDIS, the SoLID program on PVDIS.

Low x physics as an infinite twist (G)TMD framework: unravelling the origins of saturation

Journal Article Altinoluk, Taiga ; Boussarie, Renaud - Journal of High Energy Physics (Online)

We show how the formulations of low x physics involving Wilson line operators can be fully rewritten into an infinite twist TMD or GTMD framework, respectively for inclusive and exclusive observables. This leads to a perfect match between low x physics and moderate x formulations of QCD in terms of GTMDs, TMDs, GPDs or PDFs. We derive the BFKL limit as a kinematic limit and argue that beyond the Wandzura-Wilczek approximation, 3-body and 4-body unintegrated PDFs should be taken into account even in this regime. Finally, we analyze how saturation should be understood as three distinct effects: saturation through non-linearitiesmore »« less
