Global monopoles and massless dilatons in EinsteinCartan gravity
Abstract
A global monopole in dilatonic EinsteinCartan gravity is presented. A linearized solution representing a global monopole interacting with a massless dilaton is found where Cartan torsion does not interact with the monopole Higgs field.Computation of the geodesic equation shows that the monopoledilaton system generates a repulsive gravitational field.The solution is shown to break the linear approximation for certain values of torsion.
