Tagging partially reconstructed objects with jet substructure
Abstract
Here, we present a new tagger which aims at identifying partially reconstructed objects, in which only some of the constituents are collected in a single jet. As an example, we also focus on top decays in which either part of the hadronically decaying W or the b jet is soft or falls outside of the top jet cone. Furthermore, we construct an observable to identify remnant substructure from the decay and employ aggressive jet grooming to reject QCD backgrounds. The tagger is complementary to existing ones and works well in the intermediate boost regime where jet substructure techniques usually fail. It is anticipated that a similar tagger can be used to identify non-QCD hadronic jets, such as those expected from hidden valleys.
