Abstract

The gaussian damping factor (g.d.f.) and the new interaction vertex with the symplectic tenser are the characteristic properties of the N-point scalar-vector scattering amplitudes of the p - p ' (p < p ') open string system which realizes noncommutative geometry. The g.d.f. is here interpreted as aform factor of the Dp-brane by noncommutative U(1) current. Observing thatthe g.d.f. is in fact equal to the Fourier transform of the noncommutativeprojector soliton introduced by Gopakumar, Minwalla and Strominger, we further identify the Dp-brane in the zero slope limit with the noncommutative soliton state. It is shown that the g.d.f. depends only on the total momentum of N - 2 incoming/outgoing photons in the zero slope limit. In the description of the low-energy effective action (LEEA) proposed before, this is shown to follow from the delta function propagator and the form of the initial/final wave functions in the soliton sector which resides in the x(m) (m = p + 1 . . . p ') dependent part of the scalar field Phi (x(u), x(m)). Thethree and four point amplitudes computed from LEEA agree with string calculation. We discuss related issues which are resummation/lifting of infinitedegeneracy and conservation of momentum transverse to the Dp-brane.
