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 $\mathcal{E}\sim e^{2}v\gamma a^2/b^3$, where $\gamma$ 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 $\mathcal{E}\sim e^{2}v\gamma /a$. The spectral density of the total energy has a maximum at frequency ${\omega }_m\sim v\gamma /b$ and at ${\omega }_m\sim v\gamma /a$ for radial motion.
