HEPTopTagger subjet calibration for ATLAS
- 1. Physikalisches Institut, Universitaet Heidelberg (Germany)
Description
The HEPTopTagger is an algorithm that tries to identify hadronically decaying top quarks on an event-by-event basis. It reconstructs the top quark four-momentum by combining the two decay jets of the W boson with the jet from the tW-vertex. As a measure against pile-up and underlying event, a filtering step is applied which involves running the Cambridge/Aachen (C/A) jet algorithm with a dynamically chosen radius that adapts to the distance between the particles. The C/A jets have to be well calibrated to obtain high tagging efficiency and background rejection. The talk describes the energy calibration of the C/A jets for the ATLAS detector.
