摘要：

A search for single and multi-photon events with missing energy is performed using data collected at centre-of-mass energies between 161 GeV and 172 GeV for a total of 20.9 pb(-1) of integrated luminosity. The results obtained are used to derive the value for the nu<(nu)over bar>gamma(gamma) cross section as well as upper limits on new physics processes. (C) 1997 Published by Elsevier Science B.V.
