Abstract

The complete set of $O (α)$ QED corrections with soft photon exponentiation to the process $e p \to e X$ in mixed variables ( $y = y_{h}, Q^{2} = Q_{l}^{2}$ ) is calculated in the quark parton model, including the lepton-quark interference and the quarkonic corrections which were unknown so far. The interference corrections amount to few percent or less and become negligible at small $x$ . The leading logarithmic terms proportional to $ln (Q^{2} / m_{q}^{2})$ from radiation off quarks are discussed and the non-logarithmic quarkonic corrections found to be negligible for almost all experimentally accessible $x$ and $y$ .

Comments: 10 pages, latex, 5 figures, 2 tables, a uuencoded file containing the latex file and figures is available via anonymous ftp at ftp://ftp.ifh.de/pub/preprint/desy95-085.uu Section 3, 2 figures and 2 tables have been added. The revised version will appear in Phys. Lett. B
