Scattering of noncommutative (n,1) solitons

We study scattering of noncommutative solitons in (2+1)-dimensional scalar field theory. In particular, we investigate a system of two solitons with level n and n′ (the (n,n′)-system) in the large noncommutativity limit. We show that the scattering of a general (n,n′)-system occurs at right angles in the case of zero impact parameter. We also derive an exact Kähler potential and the metric of the moduli space of the (n,1)-system. We examine numerically the (n,1) scattering and find that the closest distance for a fixed scattering angle is well approximated by a function a+bn where a and b are some numerical constants.
