Photonic events with missing energy in $e^{+}e^{-}$ collisions at $\sqrt{s}=189 GeV$

Photonic events with large missing energy have been observed in e+e- collisions at a centre-of-mass energy of 189GeV using the OPAL detector at LEP. Results are presented for event topologies consistent with a single photon or with an acoplanar photon pair. Cross-section measurements are performed w...
