Kalb--Ramond dipole solution in low-energy bosonic string theory

We construct a new solution subspace for the bosonic string theory toroidally compactified to 3 dimensions. This subspace corresponds to the complex harmonic scalar field coupled to the effective 3–dimensional gravity. We calculate a class of the asymptotically flat and free of the Dirac string peculiarity solutions which describes a Kalb–Ramond dipole source with the generally nontrivial dilaton charge.
