Final Report Abstract

In terms of visibility and its impact on young careers the HEPTOP TAGGER was probably the most successful projects I ever started. Starting from the idea of Higgs tagging we have developed the leading QCD-inspired top tagger which has been shown to work in data. The Heidelberg effort has become one of the leaders in the field of jet substructure, most notably in close collaboration between our theory group and the experimental group at the Physikalisches Institut. For particle physics in Heidelberg top tagging worked as a seed for a close collaboration between our phenomenology group and the ATLAS groups and in turn for our shared Graduiertenkolleg 1940.
