TL;DR
This paper develops a formalism to include collective coordinates for off-shell D-branes, enabling calculations of their contributions to string S-matrix elements and higher-order tension corrections in both bosonic and supersymmetric models.
Contribution
It introduces a novel formalism for off-shell D-branes that allows for precise computation of their effects on string interactions and tension corrections.
Findings
Calculated off-shell D-brane contributions to S-matrix elements.
Established a 2D computation for higher order tension corrections.
Applied formalism to both bosonic and supersymmetric D-branes.
Abstract
Using a formalism developed to include collective coordinates, we calculate the contributions to S-matrix elements due to off-shell D-branes in a string coupling expansion. The formalism is further used to establish a two-dimensional computation of higher order corrections to the D-brane tension, both for the bosonic and the supersymmetric cases.
