It is shown that intrinsic transverse parton momenta p(T) in semi-inclusive deep-inelastic scattering (SIDIS) and the Drell-Yan process (DY) are very well and consistently described in the Gauss model with energy-dependent Gaussian widths. Our work solidifies the basis for future studies of p(T)-effects. We also discuss the Cahn and Boer-Mulders effect in SIDIS and DY.

Summary: The study calculates structure functions for the pion-induced Drell-Yan process, using inputs from the light-front constituent quark model and the spectator model. The implementation of TMD evolution for all asymmetries at Next-to-Leading Logarithmic precision is a first in this field. Results are in line with experimental data, aiding in data interpretation and future model assessment.

Summary: Positron beams, both polarized and unpolarized, are essential for experimental programs at the next generation of lepton accelerators, such as JLab's hadronic physics program. They provide precise understanding of electromagnetic structure of nucleons and nuclei, allow for model-independent determination of electromagnetic form factors, and enable accurate separation of contributions to lepto-production cross sections. Additionally, positron beams offer alternative tests of the Standard Model of particle physics.

Summary: The covariant parton model is expanded to systematically describe quark correlators, including all T-even twist-3 TMDs for the first time. The approach is used to evaluate fully unintegrated quark correlators, allowing for a better understanding of the model-specific relations between different TMDs. The consistency of the approach is verified through numerical results and comparison to available TMD parametrization.
