Resumen
The gravitational field of a global monopole in the context of scalar-tensor theories of gravity is investigated. The spacetime is determined by solving the equation for the scalar field and using the global monopole solution of Barriola and Vilenkin, in the weak-field approximation. A comparison is made with the results predicted by Brans-Dicke theory and general relativity.
