Fermions tunneling of Kerr-Newman-de Sitter black hole in Lorentz violation theory

In this paper, the tunneling of fermions near the event horizon of Kerr-Newman-de Sitter (KNdS) black hole is investigated in frame dragging coordinate systems, Eddington coordinate system and Painleve coordinate system by using Dirac equation with Lorentz violation theory, Feynman prescription and WKB approximation. The Hawking temperature, heat capacity and change in black hole entropy of the black hole are modified due to the presence of Lorentz violation theory. The modified Hawking temperatures, heat capacities and change in black hole entropies at the event horizon of KNdS black hole would increase or decrease depending upon the choices of ether like vectors u(a). In the absence of Lorentz violation theory, the original Hawking temperature, entropy and heat capacity are recovered.
