| Résumé : | This letter reports the results of the measurement of single photon production in the reaction e+e- → γ+ invisible particles at centre-of-mass energies √s = 130 and 136 GeV and an integrated luminosity of 5.83 pb-1, collected with the DELPHI detector at LEP. The signal is compatible with the prediction of the Standard Model for the process e+e- → vv̄γ, and the number of neutrino families has been determined to be Nv, = 3.1 ± 0.6. Limits have been derived on anomalous neutral gauge boson couplings and on compositeness in the framework of a specific model. |
