Detailed Description

Description: This is a tagger to identify boosted top quark jets.

Implementation: We input the jets from CATopJetProducer and make kinematic cuts on the jet mass and the minimum invariant mass pairing of the subjets. Described in "Top-tagging: A Method for Identifying Boosted Hadronic Tops" David E. Kaplan, Keith Rehermann, Matthew D. Schwartz, Brock Tweedie arXiv:0806.0848v1 [hep-ph]

Produces: A list of pair<Jet,CATopJetTagInfo> that represents the tag decision.
