heal.abstract	The contribution of the QCD high-twist subprocess γq→πq′ to the inclusive cross section for e+ e- → e+ e- + π± + X is calculated both in the PETRA/PEP and the LEP energy range, in the equivalent-photon approximation. Superposed on the Born cross section and its O(αs) correction, it gives agreement with the data at relatively low transverse momenta. It is suggested that this high-twist contribution may be further isolated experimentally by triggering simultaneously on both a fast hadron and the opposite-side jet. © 1986 Springer-Verlag.	en
