Bremstrahlung in wormhole spacetime with infinitely short throat
Abstract
We consider the total energy loss and spectral density of uniformly moving electrically charged particles in the spacetime of a wormhole with an infinitely short throat. We show that the total energy loss $\mathcal{E} \sim e^2vγa^2/b^3$, where $γ$ is relativistic factor, $a$ is the radius of the wormhole's throat and $b$ is the impact factor. The spectrum of the energy for particles radially moving through the wormhole's throat $\mathcal{E} \sim e^2vγ/a$. The spectral density of the total energy has a maximum at frequency $ω_m \sim vγ/b$ and at $ω_m \sim vγ/a$ for radial motion.
