String amplitude calculations agree with theoretical constraints

Long-range interactions are characterized by spin effects

Abstract

The long-range, spin-dependent forces between D0-branes are related to long-range fundamental string interactions using duality. These interactions can then be computed by taking the long distance non-relativistic expansion of string four-point amplitudes. The results are in accord with the general constraints of Matrix Theory.
