Dipolarity: Using Color
Information in Top Tagging
Abstract:
A new jet observable, dipolarity, is introduced that can distinguish
whether a pair of subjets arises from a color singlet source. This
observable is incorporated into the HEPTopTagger and is shown to
improve discrimination between top jets and QCD jets for moderate to
high pT.
