Worldsheet Instantons and a Null String Limit of Born-Infeld Theory
Get PDFFor a superstring theory in four spacetime dimensions, we propose a
modification of the Born-Infeld action that possesses a well-defined
tensionless limit. We interpret this as describing the effective target space
dynamics of null strings on a D3-brane. We argue that such a modification can
be induced by nonperturbative contributions from instantons in the worldsheet
sigma-model describing string propagation on the brane.Comment: 11 pages; Comments and references adde
