Neutrino from decays of intermediate w+- and z° bosons

  • S. M. Bilenky
  • B. Pontecorvo


In the present note we consider the following points: i) the W+- decay (and not Z°-decay !) origin of usual neutrino beams ; ii) the possible existence of ≪ sterile ≫ neutrinos and the purely phenomenological possibility (entirely out of the framework of the standard electroweak theory) that in Z°-decay there are channels in which sterile neutrinos are emitted; iii) oscillations of neutrinos of W+--decay and Z°-decay nature.
