Description
The performance of top taggers, for example in resonance searches, can be significantly enhanced through an increased set of variables, with a special focus on final-state radiation. We study the production and the decay of a heavy gauge boson in the upcoming LHC run. For this purpose we use a new version of the HEPTopTagger which now includes an optimal choice of the size of the fat jet, N-subjettiness, and Qjets. For constant signal efficiency, the multivariate analysis achieves an increased background rejection by up to a factor 30 compared to our previous tagger.
