Anomalous Higgs Boson Contribution to e^+ e^- \to b \bbar γat LEP2

Abstract

We study the effect of anomalous $H\gamma \gamma$ and $HZ\gamma$ couplings, described by a general effective Lagrangian, on the process $e^{+}{e}^{-}\to b\bar{b}\gamma$ at LEP2 energies. We include the relevant irreducible standard model background to this process, and from the photon energy spectrum, we determine the reach of LEP2 to unravel the anomalous couplings by analyzing the significance of the signal for Higgs boson with mass up to $150$ GeV.
