Bounds on the anomalous HZγ vertex arising from the process e^+e^-to τ^+ τ^- γ

We obtain limits on the anomalous coupling $HZ\gamma$ through data published by the L3 Collaboration on the process $e^+e^-\to \tau^+\tau^- \gamma$. Our analysis leads to bounds on this coupling of order $10^{-2}$, for an intermediate mass Higgs boson $115 < M_H < 145$ $GeV$, two orders of magnitude above the Standard Model prediction.
