Semi-inclusive deep inelastic scattering (SIDIS) is a key QCD process used to probe the structure of hadrons, and one which will be studied in detail at the upcoming Electron-Ion Collider. Using the NNLL threshold resummation, the authors are able to extract approximate NNLO corrections, providing an important step towards full higher-precision calculations.
