  We present a new cosmological model that mimics the Lambda Cold Dark Matter
by using a stealth field. This kind of field is characterized as not coupling
directly to gravity; however, it is connected to the underlying matter content
of the universe model. As is known, stealth fields do not back-react on the
space-time; however, their mimicry skills show how this field and its
self-interaction potential determines the cosmic evolution. We show the study
of the simplest model that can be developed with the stealth field.
