Query: Vacuumless cosmic strings in Einstein Cartan theory   The gravitational fields of vacuumless global and gauge strings have been
investigated in the context of Einstein Cartan theory under the weak field
assumption of the field equations. It has been shown that global string and
gauge string can have only repulsive gravitational effect on a test particle.
