Brans-Dicke wormholes endowed with torsion
Luis A. Anchordoqui
TL;DR
This paper presents a traversable wormhole solution within Brans-Dicke theory incorporating torsion, highlighting the limitations of the scalar field in supporting exotic matter necessary for wormhole stability.
Contribution
It introduces a novel wormhole solution in Brans-Dicke theory with torsion, using massive thin shells, and analyzes the scalar field's role in exoticity.
Findings
The solution reduces to general relativity for large coupling parameter.
The Brans-Dicke scalar cannot serve as the exotic matter source.
The wormhole is traversable with the proposed method.
Abstract
A two-way traversable wormhole solution in Brans-Dicke theory with torsion is obtained using the method of massive thin shells. The solution goes over general relativity for an infinite large value of the coupling parameter, however, the Brans-Dicke scalar could never be the ``carrier'' of exoticity that threads the wormhole throat.
