Query: Exact metric for the exterior of a global string in the Brans-Dicke
  theory   We determine in closed form the general static solution with cylindrical
symmetry to the Brans-Dicke equations for an energy-momentum tensor
corresponding to the one of the straight U(1) global string outside the core
radius assuming that the Goldstone boson field takes its asymptotic value
