  We consider a locally supersymmetric theory where the Planck mass is replaced
by a dynamical superfield. This model can be thought of as the Minimal
Supersymmetric extension of the Brans-Dicke theory (MSBD). The motivation that
underlies this analysis is the research of possible connections between Dark
Energy models based on Brans-Dicke-like theories and supersymmetric Dark Matter
scenarios. We find that the phenomenology associated with the MSBD model is
very different compared to the one of the original Brans-Dicke theory: the
gravitational sector does not couple to the matter sector in a universal metric
way. This feature could make the minimal supersymmetric extension of the BD
idea phenomenologically inconsistent.
