| contents | Universality classes of new physics models featuring narrow boson resonances produced through strongly interacting initial states in proton-proton collisions and with enhanced decays to di-tau final states are classified. Spin-zero scalar or pseudoscalar bosons with chirality-violating fermion couplings can induce potentially significant di-lepton non-universality in the bottomonium mass region, with up to many hundreds of nanobarns of direct production total cross section in proton-proton collisions at the Large Hadron Collider. Conversely, mass suppressed chirality-violating couplings of spin-zero bosons to di-electrons maintain di-lepton universality to a high degree in the same mass region at electron-positron colliders. Simultaneous measurement and comparison of integrated resonant prompt di-electron, di-muon, and di-tau mass spectra at the Large Hadron Collider in the bottomonium mass region could be sensitive to the existence of new boson resonances with enhanced di-tau decays, or likewise bottomonium states with non-Standard Model enhanced di-tau decay modes. |
