Description
Driven by the high-precision demands of the upcoming Electron-Ion Collider (EIC), this talk presents the computation of the next-to-next-to-next-to-leading order QCD corrections to the semi-inclusive deep-inelastic scattering (SIDIS) cross section. To systematically handle the intricate infrared singularities at this order, we introduce a novel two-dimensional transverse-momentum subtraction formalism. I will outline this theoretical framework and discuss the phenomenological impact of the corrections on key kinematic observables.
