Abstract

We develop a new method for tagging jets produced by hadronically decaying top quarks. The method is an application of shower deconstruction, a maximum information approach that was previously applied to identifying jets produced by Higgs bosons that decay to bb¯. We tag an observed jet as a top jet based on a cut on a calculated variable χ that is an approximation to the ratio of the likelihood that a top jet would have the structure of the observed jet to the likelihood that a nontop QCD jet would have this structure. We find that the shower deconstruction based tagger can perform better in discriminating boosted top quark jets from QCD jets than other publicly available tagging algorithms.
