Tachyon condensation on the intersecting brane-antibrane system

Abstract

We generalize our study of the tachyon condensation on the brane-antibrane system [hep-th/0403147] to the intersecting brane-antibrane system. The supergravity solutions of the intersecting brane-antibrane system are characterized by five parameters. We relate these parameters to the microscopic physical parameters, namely, the number of D$p$-branes ($N_1$), the number of $\bar{\mathrm{D}}p$-branes (${\bar{N}}_1$), the number of D$(p-4)$-branes ($N_2)$, the number of $\bar{\mathrm{D}}(p-4)$-branes (${\bar{N}}_2$) and the tachyon vev $T$. We show that the solution and the ADM mass capture all the required properties and give a correct description of the tachyon condensation for the intersecting brane-antibrane system.
