Jet Dipolarity: Top Tagging with Color Flow
Anson Hook🇺🇸 · Martin Jankowiak🇺🇸 · Jay G. Wacker🇺🇸
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.
