Search for W' bosons through decays to boosted-top and boosted-bottom jets

We propose a novel model-independent method to search for W' bosons at the Large Hadron Collider by looking at dijets where one jet is identified as a boosted-top jet and another jet is tagged as a boosted-bottom jet. Performing a detector simulated signal and background study, we demonstrate that the reach in effective coupling g' is improved over existing analysis methods by up to factor of 2 for W' masses above 1.5 TeV, and the reach in mass is extended by 600 GeV to 2.6 TeV at an 8 TeV Large Hadron Collider. We introduce a method for distinguishing high-energy b jets from light-quark jets, and describe a previously unexplored set of backgrounds to top-jets. We propose a series of data-driven samples that might be used to measure the efficiencies for these new backgrounds in the LHC data.
