Scalar-Induced Electromagnetic Radiation: Comparison with Axion-Like Particles and Implications for Modified Gravity
Wenyi Wang, Sousuke Noda, Taishi Katsuragawa
The scalar-tensor theory of gravity, a modified gravity theory, introduces a fundamental scalar field that can serve as dynamical dark energy, driving the late-time accelerated exp…
Hamiltonian Formulation of Relativistic Magnetohydrodynamic Accretion on a General Spherically Symmetric and Static Black Hole: Quantum effects on Shock States
Mustapha Azreg-Aïnou, Mubasher Jamil, Sousuke Noda
In this paper, our aim is to extend our earlier work [A. K. Ahmed et al., Eur. Phys. J. C (2016) 76:280] thereby investigating an axisymmetric plasma flow with the angular momentum…
Leading two-loop corrections to the Higgs di-photon decay in the Inert Doublet Model
Masashi Aiko, Johannes Braathen, Shinya Kanemura
Leading two-loop contributions to the di-photon decay of the Higgs boson are evaluated for the first time in the Inert Doublet Model (IDM). We employ for this calculation the Higgs…
High-energy properties of the graviton scattering in quadratic gravity
Yugo Abe, Takeo Inami, Keisuke Izumi
We obtain the matter-graviton scattering amplitude in the gravitational theory of quadratic curvature, which has term in the action. Unitarity bound is not satisfied bec…
Spectroscopy of Kerr-AdS spacetime with the Heun function: Quasinormal modes, greybody factor, and evaporation
Sousuke Noda, Hayato Motohashi
We investigate quasinormal modes, greybody factor, and Hawking evaporation of a five-dimensional Kerr-anti de Sitter (AdS) black hole by solving a wave equation for a test mass…
Evaporation of Echoing Black Holes
Naritaka Oshita, Hayato Motohashi, Sousuke Noda
We compute the graybody factor and evaporation rate of a rotating black hole in the presence of a hypothetical reflective surface slightly outside the outer horizon radius, assumin…
