Abstract
We introduce a set of gauge invariant fermion fields in fermionic coset models and show that they play a very central role in the description of several Conformal Field Theories (CFT's). In particular we discuss the explicit realization of primaries and their OPE in unitary minimal models, parafermion fields in CFT's and that of spinon fields in Wess-Zumino-Witten models (WZW) theories. The higher level case () will be briefly discussed. Possible applications to QHE systems and spin-ladder systems are addressed.
