296. Ultraviolet behavior, renormalization, and integrated TMD observables

Ted Rogers (Jefferson Lab/Old Dominion University )

4/14/21, 1:30 PM

Oral Presentation

One common application of transverse momentum dependent correlation functions is to the interpretation of scattering cross sections in terms of the intrinsic parton structure of hadrons. In such applications, one often encounters divergent ultraviolet integrals over transverse momentum. I will discuss some current and recent efforts to deal with these divergences in ways that preserve standard...

68. Electron-Ion Collider impact study on the tensor charge from a QCD global analysis of single transverse-spin asymmetries

Zhongbo Kang (University of California Los Angeles)

4/14/21, 1:50 PM

Oral Presentation

We study the impact of the Electron-Ion Collider (EIC) on the phenomenological extraction of the tensor charge from a QCD global analysis of single transverse-spin asymmetries (SSAs). We generate EIC pseudo-data for the Collins effect in semi-inclusive deep-inelastic scattering for proton and He-3 beams across multiple energy configurations. We find a significant reduction in the...

148. Factorized approach to radiative corrections for inelastic lepton-hadron collisions

Nobuo Sato (Jefferson Lab)

4/14/21, 2:10 PM

Oral Presentation

We propose a new factorized approach to QED radiative corrections (RCs) in inclusive and semi-inclusive lepton-hadron deep-inelastic scattering. The method allows the systematic resummation of the logarithmically enhanced into factorized lepton distribution and fragmentation (or jet) functions that are universal for all final states. The new approach provides a uniform treatment of RCs for the...

156. Study of unpolarized TMDs in SIDIS

Chiara Bissolotti (University of Pavia and INFN)

4/14/21, 2:30 PM

Oral Presentation

We present our recent preliminary results on unpolarized Transverse-Momentum Dependent (TMD) Parton Distribution Functions (PDFs) and Fragmentation Functions (FFs) from a study of Semi-Inclusive Deep-Inelastic Scattering (SIDIS) data. The analysis is performed in the TMD factorization framework and is a key step for the study of future data from the Electron-Ion Collider. We also provide an...

86. Final HERMES results on azimuthal single- and double-spin asymmetries in SIDIS off transversely polarized protons

Markus Diefenthaler (Jefferson Lab)

4/14/21, 2:50 PM

Oral Presentation

We summarize the recently published HERMES results on azimuthal single-spin (SSA) and double-spin asymmetries (DSA) in semi-inclusive leptoproduction of pions, charged kaons, protons, and antiprotons from transversely polarized protons. The comprehensive data set on SSA and DSA include the previously published HERMES results on Collins and Sivers asymmetries, the analysis of which has been...
