Semiclassical S $$ \mathcal{S} $$ -matrix and black hole entropy in dilaton gravity

Abstract We use complex semiclassical method to compute scattering amplitudes of a point particle in dilaton gravity with a boundary. This model has nonzero minimal black hole mass M cr . We find that at energies below M cr the particle trivially scatters off the boundary with unit probability. At h...
