Speaker: Yevgeny Kats (Rutgers)It is quite easy to imagine new particles that, produced in pairs, will decay to quarks and/or gluons, and possibly missing energy. Measuring cross-sections for such particles and determining their quantum numbers, and even discovering them, can be non-trivial. We suggest that valuable information can be obtained by measuring the resonant signals of the near-threshold QCD bound states of these particles. If the particles are charged, the resulting signatures include photons and leptons and are sufficiently rich for unambiguously determining their various quantum numbers, including the charge, color representation and spin, and obtaining a precise measurement of the mass. These signals provide new well-motivated benchmark models for resonance searches in the dilepton, diphoton, photon+jet and dijet channels, which already constrain certain ranges of parameters.
