Description
We explore the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed $\mathcal{O}(1/Q^2)$ terms in the Wandzura–Wilczek-type approximation, which consists in systematically assuming that $\bar{q}gq$-correlators are much smaller than $\bar{q}q$-correlators. Under the applicability of Wandzura–Wilczek-type approximations, certain relations among TMDs occur which will be used to approximate SIDIS cross-section by a smaller subset of TMDs. We further discuss the applicability of the Wandzura–Wilczek-type approximations on the basis of available data.
