In extensions of the standard model, light scalar particles are often possible because of symmetry considerations. We study the decay of the $Z$ boson into such particles. In particular, we consider for illustration the scalar sector of a recently proposed model of the 17-keV neutrino which satisfies all laboratory, astrophysical, and cosmological constraints.
