Title: Challenges with large transverse momentum in semi-inclusive deeply inelastic scattering

Abstract

We survey the current phenomenological status of semi-inclusive deep inelastic scattering at moderate hard scales and in the limit of very large transverse momentum. As the transverse momentum becomes comparable to or larger than the overall hard scale, the differential cross sections should be calculable with fixed order pQCD methods, while small transverse momentum (TMD factorization) approximations should eventually break down. We find large disagreement between HERMES and COMPASS data and fixed order calculations done with modern parton densities, even in regions of kinematics where such calculations should be expected to be very accurate. Possible interpretations are suggested.

Analytical Computation of Energy-Energy Correlation at Next-to-Leading Order in QCD

Journal Article Dixon, Lance J. ; Luo, Ming-xing ; Shtabovenko, Vladyslav ; ... - Physical Review Letters

Here, the energy-energy correlation (EEC) between two detectors in e⁺e^– annihilation was computed analytically at leading order in QCD almost 40 years ago, and numerically at next-to-leading order (NLO) starting in the 1980s. We present the first analytical result for the EEC at NLO, which is remarkably simple, and facilitates analytical study of the perturbative structure of the EEC. We provide the expansion of the EEC in the collinear and back-to-back regions through next-to-leading power, information which should aid resummation in these regions.

Measurement of TMDs in Semi-Inclusive DIS

Journal Article Joosten, Rainer - AIP Conference Proceedings

Over the past decades, the colinear parton model has been very successful in describing the structure of nucleons. However, in the past years it became evident, that to fully describe the structure of the nucleon this picture has to be extended taking into account the transverse momentum of the partons. This gives rise to a new set of distribution and fragmentation functions entering the cross sections, namely the transverse momentum dependent (TMD) functions.The measurement of these functions in semi-inclusive deep inelastic scattering (SIDIS) in the framework of the COMPASS and HERMES experiments is presented in this contribution.

Extraction of the worm-gear TMD _g1t from COMPASS, HERMES and JLab data on semi-inclusive DIS

Journal Article Bhattacharya, Shohini ; Kang, Zhong-Bo ; Metz, Andreas ; ... - PoS - Proceedings of Science

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 DISmore »« less

Collinear factorization in wide-angle hadron pair production in $e^{+} e^{-}$ annihilation

Journal Article Moffat, E. ; Rogers, T. C. ; Sato, N. ; ... - Physical Review D

We compute the inclusive unpolarized dihadron production cross section in the far from back-to-back region of e(+)e(-) annihilation in leading order pQCD using existing fragmentation function fits and standard collinear factorization, focusing on the large transverse momentum region where transverse momentum is comparable to the hard scale (the center-of-mass energy). We compare with standard transverse-momentum-dependent (TMD) fragmentation function-based predictions intended for the small transverse momentum region with the aim of testing the expectation that the two types of calculation roughly coincide at intermediate transverse momentum. We find significant tension, within the intermediate transverse momentum region, between calculations done with existingmore »« less
