We argue that the Dirac-Born-Infeld (DBI) action coupled to a tachyon, that is known to reproduce some aspects of open string dynamics, can be obtained from open string theory in a certain limit,â€¦ (More)

We study a class of near-BPS operators for a complex 2-parameter family of N = 1 superconformal Yang-Mills theories that can be obtained by a Leigh-Strassler deformation of N = 4 SYM theory. Weâ€¦ (More)

We construct an approximate solution for an asymptotically flat, neutral, thin rotating black ring in any dimension D â‰¥ 5 by matching the near-horizon solution for a bent boosted black string, to aâ€¦ (More)

Using the Batalin-Vilkovisky formalism we provide a detailed analysis of the N S sector of boundary superstring field theory. We construct explicitly the relevant BV structure and derive the masterâ€¦ (More)

In a previous paper (hep-th/0304045) it has been argued that tachyonic Dirac-Born-Infeld (DBI) actions can be obtained from open string theory in a limit, which generalizes the usual massless DBIâ€¦ (More)

Using exact boundary conformal field theory methods we analyze the D-brane physics of a specific four-dimensional non-critical superstring theory which involves the N = 2 SL(2)/U(1) Kazama-Suzukiâ€¦ (More)

We initiate a systematic scan of the landscape of black holes in any spacetime dimension using the recently proposed blackfold effective worldvolume theory. We focus primarily on asymptotically flatâ€¦ (More)

We discuss the non-perturbative behavior of the U(1)R symmetry in N = 2 superconformal Chern-Simons theories coupled to matter in the (anti)fundamental and adjoint representations of the gauge group,â€¦ (More)

Large-N matrix models coupled via multitrace operators are used to define, via appropriate double-scaling limits, solvable models of interacting multi-string theories. It is shown that although suchâ€¦ (More)

We report an exact solution of 2- and 3-point functions of chiral primary fields in SU(2) N=2 super-Yang-Mills theory coupled to four hypermultiplets. It is shown that these correlation functions areâ€¦ (More)
