We study the mass spectra, production, and decay properties of the lightest supersymmetric CP-even and CP-odd Higgs bosons in models with spontaneously broken R parity. We compare the resulting mass spectra with expectations of the minimal supersymmetric standard model (MSSM), stressing that the model obeys the upper bound on the lightest CP-even Higgs boson mass. We discuss how the presence of the additional scalar singlet states affects the Higgs production cross sections, both for the Bjorken process and the ''associated production.'' The main phenomenological novelty with respect to the MSSM comes from the fact that the spontaneous breaking of lepton number leads to the existence of the majoron, denoted J, which opens new decay channels for supersymmetric Higgs bosons. We find that the invisible decays of CP-even Higgses can be dominant, while those of the CP-odd bosons may also be sizable.
