# CLASSICAL p-BRANES FROM BOUNDARY STATE ∗

@article{Vecchia1997CLASSICALPF, title={CLASSICAL p-BRANES FROM BOUNDARY STATE ∗}, author={P. Vecchia and M. Frau and I. Pesando and S. Sciuto and A. Lerda and R. Russo}, journal={Nuclear Physics}, year={1997}, volume={507}, pages={259-276} }

We show that the boundary state description of a Dp-brane is strictly related to the corresponding classical solution of the low-energy string effective action. By projecting the boundary state on the massless states of the closed string we obtain the tension, the R-R charge and the large-distance behavior of the classical solution. We discuss both the case of a single D-brane and that of bound states of two D-branes. We also show that in the R-R sector the boundary state, written in a picture… Expand
