Leptomeson contribution to the muon g-2

Many models on the market allow for particles carrying both lepton number and color, e.g., leptoquarks and leptogluons. Some of the models with this feature can also accommodate color-singlet leptohadrons. We have found that the long-standing discrepancy between the experimental result and the Standard Model prediction for the muon anomalous magnetic moment can be explained by the effect of leptomesons with masses of a few hundred GeV and couplings to the leptons and mesons either of O(10(-2)) (vector-meson case) or of O(1) (scalar case). These new particles are testable at the current run of the LHC.
