Zero-slope limit of the compactified closed bosonic string.

Journal article

We investigate, in the low-energy limit of the closed bosonic string theory, the role of the toroidal compactification, in which the extra spatial coordinates are circular with radius R. We explicitly show that the double limit 0 and R0, performed on the tree scattering amplitude of four massless scalar particles, leads to four-dimensional amplitudes describing a diffusion due to the exchange of a scalar, spin-1, and spin-2 particle and that it is not influenced by the compactification procedure adopted. © 1994 The American Physical Society.
