The dynamics of D3-brane dyons and toric hyper-Kähler manifold Original Research Article

We find the dyonic world-volume solitons due to parallel (p, g)-strings ending on a D3-brane. These solutions preserve 14 of bulk supersymmetry. Then we investigate the scattering of well-separated dyons and find that their moduli space is a toric hyper-Kähler manifold. In addition, we present the world-volume solitons of the D3-brane which are related by duality to the M-theory configuration of two orthogonal membranes ending on an M5-brane. We show that these solitons preserve l8 of supersymmetry and compute their effective action.
