638] for the SU(2) confining string in the maximal abelian projection are a
nalysed. The distribution of the electric flux and monopole currents are pe
rfectly described by the classical equations of motion for the dual Abelian
Higgs model. The mass of the vector boson is equal to the mass of the mono
pole (Higgs particle) within numerical errors. The classical energy per uni
t length of the Abrikosov vortex reproduces 94% of the full non-Abelian str
ing tension. (C) 1999 Published by Elsevier Science B.V. All rights reserve
