摘要：

We have obtained a new exact regular black hole solution for the EGB gravity coupled with nonlinear electrodynamics in AdS space. The numerical analysis of horizon structure suggests two horizons exist: Cauchy and event. We also study the thermal properties of this black hole, which satisfy the modified first law of thermodynamics. Moreover, we analyze the local and global stability of the black hole. The P - V criticality and phase transition are also discussed. The critical exponents for the present model exactly match the mean field theory.
