Hawking radiation characteristics of Kerr–Sen black hole spacetime under Lorentz symmetry breaking

In this article, we had explored the quantum tunneling radiation Ford (Quant World Quant Phys Everyone, 2009) of Kerr–Sen black holes through the Lorentz symmetry breaking theory Tiago et al. (Lorentz Symmetry Breaking-Classical and Quantum Aspects, 2023) and had obtained the corrected black hole entropy, Hawking temperature Hawking (Nature 30: 248, 974), and quantum tunneling Weinberg (The Quantum Theory of Fields 1995) emissivity of Kerr–Sen black hole. Considering the kinetic equation of bosons under the Kerr–Sen black hole spacetime theory, we introduce an ether-like vector \(u_\alpha\) $u_{\alpha }$ into the dynamics of bosons in curved spacetime Parikh and Wilczek (Phys Rev Lett 2000), and then, we had obtained the corrected kinetic equation of bosons. Through Kerr–Sen black hole line element, we had calculated the corrected black hole entropy Bekenstein (Black Holes and Entropy, Phys. Rev. D 1973), Hawking temperature, and quantum tunneling emissivity of the Kerr–Sen black hole
