I develop an effective theory which describes black holes with quantum

mechanical horizons that is valid at scales long compared to the

Schwarzschild radius but short compared to the lifetime of the black

hole. The formalism allows one to calculate the quantum mechanical

effects in scattering processes involving black hole asymptotic states.

The EFT Wightman functions which describe Hawking radiation in the Unruh

vacuum are not Planck suppressed and are actually enhanced relative to

those in the Boulware vacuum, for which such radiation is absent. We

elaborate on this point showing how the non-Planck suppressed effects of

Hawking radiation cancel in classical observables. Applications to

inelastic gravitational scattering of point particles off quantum black

holes will be briefly discussed.
