abstract
We reconsider the issue of whether scalar-tensor theories can admit stable wormhole configurations supported by a non-trivial radial profile for the scalar field. Using a recently proposed effective theory for perturbations around static, spherically symmetric backgrounds, we show that scalar-tensor theories of "beyond Horndeski" type can have wormhole solutions that are free of ghost and gradient instabilities. Such solutions are instead forbidden within the more restrictive "Horndeski" class of theories.

Black bounces to traversable wormholes from pure gravity in four and higher dimensions
Any static spherically symmetric wormhole or black bounce with a single integration constant can be made the unique vacuum solution of some specially constructed higher-dimensional pure-metric gravity theory.
