 Single and multi-photon events with missing energy in $e^+ e^-$ collisions at 161 GeV $\sqrt{s}$ 172 GeV
 L3 Collaboration(s)
 (1997)
 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 $\nu\bar{\nu}\gamma(\gamma)$ cross section as well as upper limits on new physics processes.
