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 Poincaré-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.
