Query: Higgs Bosons in supersymmetric U(1)' models with CP Violation   We study the Higgs sector of the U(1)'-extended MSSM with CP violation. This
is an extension of the MSSM Higgs sector by one singlet field, introduced to
generate the \mu term dynamically. We are particularly interested in
non-standard decays of Higgs particles, especially of the lightest one, in the
presence of CP violating phases for \mu_{eff} and the soft parameters. We
present analytical expressions for neutral and charged Higgs bosons masses at
tree and one-loop levels, including contributions from top and bottom scalar
quark sectors. We then study the production and decay channels of the neutral
Higgs for a set of benchmark points consistent with low energy data and relic
density constraints. Numerical simulations show that a Higgs boson lighter than
2m_W can decay in a quite distinctive manner, including invisible modes into
two neutralinos (h->\chi^0\chi^0) up to 50% of the time, when kinematically
allowed. The branching ratio into h->bb, the dominant decay in the SM, is
reduced in some U(1)' models and enhanced in others, while the branching ratios
for the decays h -> \tau+ \tau-, h -> WW^* and h -> Z Z^*-> 4l are always
reduced with respect to their SM expectations. This possibility has important
implications for testing the U(1)' model both at the LHC and later at the ILC.
