Wormholes in Einstein-scalar-Gauss-Bonnet theories with a scalar self-interaction potential

Understand

We construct wormholes in Einstein-scalar-Gauss-Bonnet theories with a potential for the scalar field that includes a mass term and self-interaction terms.

• By varying the Gauss-Bonnet coupling constant we delimit the domain of existence of wormholes in these theories.
• The presence of the self-interaction enlarges the domain of existence significantly.
• There arise wormholes with a single throat and wormholes with an equator and a double throat.
