Description
The workshop will address automation of 1-loop matrix element evaluation and subtraction for real radiation needed for complete next-to-leading order calculations. The current status, most recent progress, philosophy and perspectives of both modern unitarity inspired methods and more traditional approaches will be covered. The workshop will take place in the meeting room in the Rectorate building - B.06.01 at the Grifflenberger Campus of the Bergische University of Wuppertal.
