We propose a new technique for measuring the polarization of hadronically decaying boosted top quarks. In particular, we apply a subjet-based technique to events where the decay products of the top are clustered within a single jet. The technique requires neither b-tagging nor W-reconstruction, and does not rely on assumptions about either the top production mechanism or the sources of missing energy in the event. We include results for various new physics scenarios made with different Monte Carlo generators to demonstrate the robustness of the technique.

  1. Jet Substructure Analysis for Distinguishing Left- and Right-Handed Couplings of Heavy Neutrino in $W'$ Decay at the HL-LHC

    hep-ph 2024-11 conditional novelty 5.0 of 10

    At the HL-LHC, jet substructure variables z_l, z_theta, and z_k combined with a BDT could exclude either left- or right-handed W'-to-heavy-neutrino couplings at about 1.6-2.8 sigma for benchmark masses.
