Brans wormholes

It is shown that three of the four Brans solutions of classes I--IV admit wormhole geometry. Two-way traversable wormholes in the Brans-Dicke theory are allowed not only for the negative values of the coupling parameter {ω} ({ω}-2), as concluded earlier, but also for arbitrary positive values of {ω} ({ω}{∞}). It also follows that the scalar field {φ} plays the role of exotic matter violating the weak energy condition.
