Abstract

We study the transverse polarization of hyperons produced in semi-inclusive deep inelastic scattering, epeΛXep\to e\Lambda^\uparrow X, in the framework of the collinear twist-3 factorization. The cross section from the twist-3 distribution functions and the twist-3 quark fragmentation functions is computed in the leading order with respect to the QCD coupling constant. The constraint relations among the twist-3 FFs are taken into account to simplify the formula. The formula is relevant to large-PTP_T hyperon production in the future Electron-Ion-Collider experiment.
