We describe the sample of energetic single-photon events (E gamma > 15 GeV) collected by L3 in the 1991-1993 LEP runs. The event distributions agree with expectations from the Standard Model. The data are used to constrain the ZZ gamma coupling and to set an upper limit of 4.1x10(-6) mu(B) (90% C.L.) on the the magnetic moment of the tau neutrino.

Abstract
We describe the sample of energetic single-photon events (E gamma > 15 GeV) collected by L3 in the 1991-1993 LEP runs. The event distributions agree with expectations from the Standard Model. The data are used to constrain the ZZ gamma coupling and to set an upper limit of 4.1x10(-6) mu(B) (90% C.L.) on the the magnetic moment of the tau neutrino.File in questo prodotto:
