Abstract
$D$-brane boundary states for type II superstrings are constructed by enforcing the conditions that preserve half of the space-time supersymmetry. A light-cone coordinate frame is used where time is identified as one of the coordinates transverse to the brane's (euclidean) world-volume so that the $p$-brane is treated as a $(p+1)$-instanton. The boundary states have the superspace interpretation of top or bottom states in a light-cone string superfield. The presence of a non-trivial open-string boundary condensate give rise to the familiar $D$-brane source terms that determine the (linearized) Born--Infeld-like effective actions for $p$-branes and the (linearized) equations of motion for the massless fields implied by the usual $p$-brane ansatze. The `energy' due to closed string exchange between separate $D$-branes is calculated (to lowest order in the string coupling) in situations with pairs of parallel, intersecting as well as orthogonal branes -- in which case the unbroken supersymmetry may be reduced. Configurations of more than two branes are also considered in situations in which the supersymmetry is reduced to $1/8$ or $1/16$ of the full amount. The Ward identities resulting from the non-linearly realized broken space-time supersymmetry in the presence of a $D$-brane are also discussed.
