The gamma-ray burst arising from neutrino pair annihilation in the static and spherically symmetric black-hole-like wormholes

Autor: Shi, Yuxuan, Cheng, Hongbo

Publikováno v: Journal of Cosmology and Astroparticle Physics 2310(2023)062

We look into the neutrino-antineutrino pair ($\nu+\bar{\nu}\longrightarrow e^{-}+e^{+}$) annihilation in the Damour-Solodukhin wormhole spacetime whose metric component involves a shift in contrast to the similar black hole. The deep analysis of the

The shadow and gamma-ray bursts of a Schwarzschild black hole in asymptotic safety

Autor: Shi, Yuxuan, Cheng, Hongbo

We research on the neutrino pair annihilation $\nu+\overline{\nu}\longrightarrow e^{-}+e^{+}$ around a massive source in asymptotic safety. Since neutrinos and photons have the same geodesic equation around black holes, we can estimate the radius whe

The Horava-Lifshitz Modifications of the Casimir effect at finite temperature revisted

Autor: Cheng, Hongbo

Publikováno v: The European Physical Journal C82(2022)1032

We proceed with the study of the Casimir force for parallel plates at finite temperature in the Horava-Lifshitz (HL) theory. We find that the HL exponent can not be chosen as an integer, or the Casimir energy will be a constant and further the Casimi

The neutrino pair annihilation ($\nu\bar{\nu}\longrightarrow e^{-}e^{+}$)around a massive source with an $f(R)$ global monopole

Autor: Shi, Yuxuan, Cheng, Hongbo

Publikováno v: EPL(Europhysics Letters) 140(2022)49001

In this work we investigate the neutrino pair annihilation around a gravitational object involving an $f(R)$ global monopole. We derive and calculate the ratio $\frac{\dot{Q}}{\dot{Q_{Newt}}}$ meaning that the energy deposition per unit time is over
