Infra-red dynamics of D1-branes at the conifold

Abstract

We study the infra-red dynamics of D1-branes at the conifold. We show using methods developed to study the infra-red dynamics of (4, 4) theories, the infra-red degrees of freedom of the (2, 2) theory of a single D1-brane at the conifold is that of a linear dilaton with background charge of √ 2 and a compact scalar. The gauge theory of N D1-branes at the conifold is used to formulate the matrix string in the conifold background.
