  The characteristic feature of the spontaneous symmetry breaking is the
presence of the Goldstone mode(s). For the conformal symmetry broken
spontaneously the corresponding Goldstone boson is the dilaton. Coupling an
arbitrary system to the dilaton in a consistent (with quantum corrections) way
has certain difficulties due to the trace anomaly. In this paper we present the
approach allowing for an arbitrary system without the gravitational anomaly to
keep the dilaton massless at all orders in perturbation theory, i.e. to build a
theory with conformal symmetry broken spontaneously.
