N2 - In this paper we present two (a priori independent) derivations of theeikonal operator in string-brane scattering. The rst one is obtained by summingsurfaces with any number of boundaries, while in the second one the eikonal operatoris derived from the three-string vertex in a suitable light-cone gauge. This secondderivation shows that the bosonic oscillators present in the leading eikonal operatorare to be identied with the string bosonic oscillators in a suitable light-cone gauge,while the rst one shows that it exponentiates recovering unitarity. This paper is areview of results obtained in Refs. [1]. and [2].
