@article{Azad2020TransmissionOL, title={Transmission of low-energy scalar waves through a traversable wormhole}, author={Bahareh Azad and Farhang Loran and Ali Mostafazadeh}, journal={arXiv: General Relativity and Quantum Cosmology}, year={2020} }

We study the scattering of low-energy massless and massive minimally coupled scalar fields by an asymptotically flat traversable wormhole. We provide a comprehensive treatment of this problem offering analytic expressions for the transmission and reflection amplitudes of the corresponding effective potential and the absorption cross section of the wormhole. Our results, which are based on a recently developed dynamical formulation of time-independent scattering theory, apply to a large class of…
