Standard model large-ET processes and searches for new physics at HERA

Existing and missing calculations of standard model processes producing large transverse energy in electron-proton interactions at HERA are reviewed. The adequacy of the existing standard model Monte Carlo programs for generic searches of exotic processes is analysed. This is a shortened Version of Krasny M W and Spiesberger H (1998 Preprint hep-th 9901359).
