Traversable l-wormholes supported by ghost scalar fields

We present new, asymptotically flat, static, spherically symmetric and traversable wormhole solutions in general relativity which are supported by a family of ghost scalar fields with quartic potential. This family consists of a particular composition of the scalar field modes, in which each mode is characterized by the same value of the angular momentum number , yet the composition yields a spherically symmetric stress?energy?momentum and metric tensor. For our solutions reduce to wormhole configurations which had been reported previously in the literature. We discuss the effects of the new parameter on the wormhole geometry including the motion of free-falling test particles.
