Hawking temperature from scattering off the two-dimensional black hole

We calculate the reflection and transmission coefficients for scattering of string fields (tachyon and two graviton-dilaton modes) off the two-dimensional black hole. From the on-shell reflection coefficient of the tachyon scattering, we extract an expression for the Hawking temperature. In a certain limit, this is consistent with the limit of μ → 0 of De Alwis and Lykken [3] and the statistical result.
