Bremstrahlung in wormhole spacetime with infinitely short throat

Khusnutdinov, Nail

Original · EN

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 e²vγa²/b³, 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 E e²vγ/a. The spectral density of the total energy has a maximum at frequency ωₘ vγ/b and at ωₘ vγ/a for radial motion.
