Jet Dipolarity: Top Tagging with Color Flow
arXiv:1102.1012 · doi:10.1007/JHEP04(2012)007
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.
