Information Loss Paradox Tested on Chiral Fermion Coupled to a   Background Dilatonic Field
  A model where chiral boson is coupled to a background dilatonic field is considered to study the s-wave scattering of fermion by a back ground dilatonic black hole. Unlike the conclusion drawn in \cite{MIT} it is found that the presence of chiral fermion does not violate unitarity and information remains preserved. Regularization plays a crucial role on the information paradox.
