Role of Faddeevian anomaly in the s-wave scattering of chiral fermion off dilaton black holes towards preservation of information
It was found that s-wave scattering of chiral fermion off dilaton black-hole
when studied with a model generated from the chiral Schwinger model with
standard Jackiw-Rajaraman type of anomaly provided information non preserving
result. However this scattering problem when studied with a model generated
from chiral Schwinger model with generalized Faddeevian type of anomaly.
rendered information preserving result and it had well agreement with Hawking's
revised proposal related to information loss. A minute and equitable
investigation in detail has been carried out here to show how Faddeevian type
of anomaly scores over the Jackiw-Rajaraman type of anomaly in connection with
the s-wave scattering of chiral fermion of dilaton black-hole related to
preservation of information.Comment: 11 pages latex file: To appear in Nucl. Phys.
