| Popis: | In this paper, the tunneling of vector boson particles across the event horizon of Kerr–Newman–de Sitter (KNdS) black hole is investigated using the WKB approximation and Hamilton–Jacobi ansatz to Proca equation. The tunneling probability and radiation spectrum at the event horizon of KNdS black hole is obtained. The modified Hawking radiation of stationary and non-stationary KNdS black hole are also investigated using the Rarita–Schwinger ansatz to the deformed Hamilton–Jacobi method and new tortoise coordinate transformation. It is observed that the modified Hawking temperatures near the event horizon for both stationary and nonstationary space times are dependent on the black hole parameters. |
