Searchesfor new leptophobic resonances at high energy colliders usuallytarget their decay modes into pairs of light quarks, top quarks, orstandard model bosons. Additional decay modes may also be present,producing signatures to which current searches are not sensitive. Weinvestigate the performance of generic searches that look forresonances decaying into two large-radius jets. As benchmark for ouranalysis we use a supersymmetric U(1)′ extension of the StandardModel, the so-called UμνSSM, where all the SM decay modes of the Z′boson take place, plus additional (cascade) decays into new scalars.The generic searches use a generic multi-pronged jet tagger and takeadvantage of the presence of b quarks in the large-radius jets, andare sensitive to all these Z′ decay modes (except into lightquarks) at once. For couplings that are well below currentexperimental constraints, these generic searches are sensitive at the3σ−4σ level with Run 2 LHC data.p { margin-bottom: 0.25cm; line-height: 120%; background: transparent }a:link { color: #000080; so-language: zxx; text-decoration: underline }
