Query: Ghosts in the Matter Forms   In this paper we study the matter form of the conformal and super-conformal
ghosts action. That is, the ghost fields will be expressed in terms of some
scalar and spinor fields. Thus, we obtain a two-dimensional covariant action in
the matter form, $i.e.$ $S_g$. The Poincar\'e-like symmetries and various
supersymmetries of this covariant action are analyzed. The signatures 10+2 and
11+3 for the total target space of the superstring theory also will be
discussed.
