Abstract
Assuming a nonvanishing neutrino magnetic moment mu, the tau-neutrino properties are investigated in the process positron-electron decay to nu(bar-nu)(gamma) from the single photon searches at colliders. For a large value of neutrino mass the interference between the diagrams with Z(sup 0) and gamma exchange becomes important and should be taken into account in the positron-electron experiments. Some cosmological and astrophysical impliciations of this new heavy neutrino scenario are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
