Abstract
The production of single photons has been studied in the reaction e(+)e(-) --> gamma +invisible particles at centre-of-mass energies of 183 GeV and 18 9 GeV. A previously published analysis of events with multiphoton final sta tes accompanied by missing energy has been updated with 189 GeV data. The d ata were collected with the DELPHI detector and correspond to integrated lu minosities of about 51 pb(-1) and 158 ph(-1) at the two energies. The numbe r of light neutrino families is measured to be 2.84 +/- 0.15(stat) +/- 0.14 (syst). The absence of an excess of events beyond that expected from Standa rd Model processes is used to set limits on new physics as described by sup ersymmetric and composite models. A limit on the gravitational scale is als o determined.
