Interaction of Dynamical Fractional Branes with Background Fields: Superstring Calculations

Abstract

We compute the boundary state corresponding to a fractional D$p$-brane with transverse motion and internal background fields: Kalb-Ramond and a $U(1)$ gauge field. The spacetime has the orbifold structure ${\mathbb{R}}^{1,5}\times {\mathbb{C}}^2/{\mathbb{Z}}_2$. The calculations are in the superstring theory. Using this boundary state we shall obtain the interaction amplitude between two parallel moving fractional D$p$-branes. We shall extract behavior of the interaction amplitude for large distances of the branes.
