Determination of the number of light neutrino species
We have measured the cross-section of the production of single photon events in e + e- collisions near the Z ° resonance. For an integrated luminosity of 9.6 pb -1, we have observed 202 single photon candidates with energy between 0.9 and 3.5 GeV in the polar angular region between 45 ° and 135 °. A...
