Abstract

Searches for new hadronic resonances typically focus on high-mass spectra, due to overwhelming QCD backgrounds and detector trigger rates. We present a study of searches for relatively low-mass hadronic resonances at the LHC in the case that the resonance is boosted by recoiling against a well-measured high-pTp_{\textrm{T}} probe such as a muon, photon or jet. The hadronic decay of the resonance is then reconstructed either as a single large-radius jet or as a resolved pair of standard narrow-radius jets, balanced in transverse momentum to the probe. We show that the existing 2015 LHC dataset of pppp collisions with Ldt=4 fb1\int\mathcal{L}dt = 4\ \mathrm{fb}^{-1} should already have powerful sensitivity to a generic ZZ' model which couples only to quarks, for ZZ' masses ranging from 20-500 GeV/c2^2.
