  ABSTRACT: The constraints on the number of neutrinos generations, g'1 coupling and Z- Z′ mixing angle through the invisible width method, and in the framework of a U(1)B-L model are obtained. Based on the experimental value reported by the LEP for the rate , we obtained a bound on the g'1 coupling, . In addition, we derive 90% C.L. bounds on the Z- Z′ mixing angle , improving the existing bounds by one order of magnitude.
