Idea

bound states of Dp-branes with D(p+4)-branes.

Properties

As Yang-Mills instantons in the Chan-Paton gauge field

Due to the higher WZW term D p+4C p+1FF\propto \int_{D_{p+4}} C_{p+1} \wedge \langle F \wedge F \rangle in the Green-Schwarz sigma model for D(p+4)-branes, Yang-Mills instantons in the Chan-Paton gauge field on D(p+4)D (p+4)-branes are equivalently Dp-D(p+4)-brane bound states (see e.g. Polchinski 96, 5.4, Tong 05, 1.4).

Relation to instantons

The argument that Yang-Mills instantons in the Chan-Paton gauge field on a D(p+4)-brane are equivalent to Dp-D(p+4) brane bound states goes back to
