Abstract

In the framework of the SU(2) x U(1) x U(1) gauge model the rare decays Z --> J/psi(gamma) + X (where X is the light gauge boson corresponding to the extra U(1) group) are investigated. Using the model of independent restrictions to the coupling constant and mass of X-boson, it is shown that, in some region of parameters, these decay rates (greater-than-or-equal-to 10 keV) can be measurable in LEP with high luminosity.
