The magnetic moment of the rho-meson is calculated in the framework of a low-energy effective field theory of the strong interactions. We find that the complex-valued strong interaction corrections to the gyromagnetic ratio are small leading to a value close to the real tree level result, g(rho) = 2. This is in a reasonably good agreement with the available lattice QCD calculations for this quantity. (C) 2014 The Authors. Published by Elsevier B.V.
