Identifying Hadronically Decaying Vector Bosons Merged into a Single Jet

In the new energy regime of the LHC, it is becoming increasingly important for new physics searches to identify single jet objects which originate from and contain the decay products of a hadronically decaying massive W boson produced with high transverse momentum. A number of observables are explored for identifying these "W-jets". An algorithm is defined to identify jets originating from hadronically decaying W bosons for different signal scenarios. The efficiency for tagging W-jets is presented and comparisons are made between data and simulation. All the techniques discussed in identifying W-jets are applicable for other hadronic two-prong decays such as those from Z and Higgs bosons.
