Abstract: We use the Parikh–Wilczek method to study the Hawking radiation of a Kerr–Sen black hole via tunneling. We show that corrections to the emission rate exist and that the corrected radiation spectrum deviates from the purely thermal spectrum. Our result is consistent with an underlying unitary theory and compatible with earlier results.

Keywords: Hawking radiation, Kerr–Sen black hole, Boltzmann factor.
