We present next-to-leading order QCD corrections for the cross sections of

$\ell p^\uparrow\to (h\,\mathrm{or}\,jet)X$ with transversely polarized initial protons.
These cross sections are known to be power-suppressed in QCD
and probe twist-3 parton correlation functions in the proton. Our calculation exhibits the full complexity of a
perturbative QCD analysis beyond leading power,... -

We explore the quark and the gluon Sivers functions in dijet production at the EIC. Our analysis includes a comprehensive investigation of the sin($\phi_S - \phi_r$) modulated cross-sections for both quark and gluon channels. Furthermore, we state the possibility of re-defining the resummation method, altering the treatment of large logarithmic corrections. We also test different models for...

In this talk I present a QED-based analog of the Sivers effect in QCD. In particular, Compton scattering off an ionized Helium-4 target is used as a process to access the Sivers effect for the electron in the atomic target.

To account for the motion of the bound electron in the Helium target, hydrogen-like wave functions in momentum space are employed.
Both the unpolarized TMD distribution...
