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 $E \sim e^{2} v γ a^{2} / b^{3}$ , 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 is $E \sim e^{2} v γ / a$ . The spectral density of the total energy has a maximum at frequency $ω_{m} \sim v γ / b$ and at $ω_{m} \sim v γ / a$ for radial motion.
