Radiation from Hayward Black Hole via Tunneling Process in Einstein-Gauss-Bonnet Gravity

One of the most promising theories for modified gravity is the einstein-gauss-bonnet (egb) gravity. in the framework of egb gravity, we intend to compute the hawking radiation of a 5-dimensional hayward black hole with a regular center and with both inner (cauchy) and outer (event) horizons. on the basis of particles in a dynamical geometry, we provide a brief derivation of hawking radiation as a tunneling process. the boltzmann factor of emission at the hawking temperature is related to the imaginary part of the action for the classically prohibited process.
