Newtonian Gravitons and D-brane Collective Coordinates in Wound String Theory

TL;DR

This paper clarifies how gravity manifests in Non-relativistic Wound string theory, revealing the role of unwound gravitons and D-brane collective coordinates through analysis of string limits and supergravity duals.

Contribution

It demonstrates the presence of unwound gravitons and D-brane collective coordinates in Wound string theory, connecting worldsheet formalism and supergravity dual descriptions.

Findings

Wound string theory contains unwound gravitons mediating long-range interactions.

Unwound strings serve as collective coordinates for D-branes.

Open and closed strings correspond to short and long strings in supergravity duals.

Abstract

Recently it was shown that NCOS theories are part of a ten-dimensional theory known as Non-relativistic Wound string theory. We clarify the sense in which gravity is present in this theory. We show that Wound string theory contains exceptional unwound strings, including a graviton, which mediate the previously discovered instantaneous long-range interactions, but are negligible as asymptotic states. Unwound strings also provide the expected collective coordinates for the transverse D-branes in the theory. These and other results are shown to follow both from a direct analysis of the effect of the NCOS limit on the parent string theory, and from the worldsheet formalism developed by Gomis and Ooguri, about which we make some additional remarks. We also devote some attention to supergravity duals, and in particular show that the open and closed strings of the theory are respectively described by short and long strings on the supergravity side.
