Hawking tunneling radiation of the spherically symmetric black holes at the Planck scale

Although the tunneling approach is fully established for black holes radiation, much work has been done to support the extension of this approach to more general settings. In this paper the Parikh-Kraus-Wilczeck proposal of black holes tunneling radiation is considered. The spherically symmetric black holes thermodynamics and tunneling radiation are studied based on the generalized uncertainty principle (GUP) and the modified dispersion relation (MDR) analysis. It is shown that entropy, temperature and the original Parikh-Kraus-Wilczek calculation of the black hole tunneling radiation receive some corrections. Through comparison, the results of these two alternative approaches are shown to be identical if one uses the suitable expansion coefficients.
