Existence of vacuum wormholes in Einsteinian cubic gravity

Journal of High Energy Physics
Wormhole solutions in gravitational theories typically require exotic matter. Here we present a wormhole solution to the field equations of Einsteinian Cubic Gravity — a phenomenological competitor to general relativity that includes terms cubic in the ...
