Abstract

We study the effect of anomalous $H γ γ$ and $HZ γ$ couplings, described by a general effective Lagrangian, on the process $e^{+} e^{-} \to b \bar{b} γ$ at CERN LEP 2 energies. We include the relevant irreducible standard model background to this process, and from the photon energy spectrum, we determine the reach of LEP 2 to unravel the anomalous couplings by analyzing the significance of the signal for a Higgs boson with a mass up to 150 GeV.
