  The conformal compensator formalism is a convenient and versatile
representation of supergravity (SUGRA) obtained by gauge fixing conformal
SUGRA. Unfortunately, practical calculations often require cumbersome
manipulations of component field terms involving the full gravity multiplet. In
this paper, we derive an alternative gauge fixing for conformal SUGRA which
decouples these gravity complications from SUGRA computations. This yields a
simplified tree-level action for the matter fields in SUGRA which can be
expressed compactly in terms of superfields and a modified conformal
compensator. Phenomenologically relevant quantities such as the scalar
potential and fermion mass matrix are then straightforwardly obtained by
expanding the action in superspace.
