World Volume Action for Fractional Branes
P. Merlatti, G. Sabella
Abstract
We study the world volume action of fractional Dp-branes of type IIA string theory compactified on the orbifold T4/Z2. The geometric relation between these branes and wrapped branes is investigated using conformal techniques. In particular we examine in detail various scattering amplitudes and find that the leading low-energy interactions are consistent with the boundary action derived geometrically.
