title = "Scattering Of Closed Strings From Many D-Branes",
abstract = "We develop an operator formalism to compute scattering amplitudes of arbitrary bosonic string states in the background of many D-branes. Specifically, we construct a suitable boundary state which we use to saturate the multi-Reggeon vertex in order to obtain the generator of multi-membrane scattering amplitudes. We explicitly show that the amplitudes with h parallel D-branes are similar to amplitudes with h−1 open string loops.",

note = "Funding Information: In this paper we develop an operator formalism that allows to compute scattering amplitudes of arbitrary string states in the presence of many D-branes. Starting from the results already achieved in the old days of string theory [ 31, we first construct a state which inserts a boundary on the world-sheet and enforces Dirichlet or Neumann boundary conditions on the string coordinates. Then, we take the multi-Reggeon vertex of the operator formalism [4,5], which describes the emission of many closed strings from a sphere, and saturate it *Work partially supported by the European Commission TMR programme ERBFMRX-CT96-0045in which R.R. is associated to Torino University. {\textquoteright} E-mail:
