| English abstract | The flavor, changing neutral current decay h → τµ is studied in a renormalizable scalar leptoquark model with no proton decay. Analytical expressions for the one-loop level contributions of a scalar leptoquark to the decay width of the process h → τµ are presented. We find a viable model parameter space via the current constraints on the muon (g − 2), the decays τ → µγ, µ → eγ, the LHC Higgs boson data and the direct leptoquark searches at the LHC. Then, we evaluate the branching ratio of the decay h → τµ induced by leptoquarks, which is of order 10−9 −10−7. We find that with the branching ratio so suppressed, it will be difficult to observe the h → τµ decay in current colliders, but potential evidence could be observed at the Future hadron-hadron Circular Collider |
