Little String Theories in Heterotic Backgrounds
E. Gava, K. S. Narain, M. H. Sarmadi
We study Little String Theories (LST) with supersymmetry arising, in a suitable double scaling limit, from 5-branes in heterotic string theory or in the heterotic-…
Instantons in Superconformal Gauge Theories and the AdS/CFT Correspondence
E. Gava, K. S. Narain, M. H. Sarmadi
We study, using ADHM construction, instanton effects in an ${\CN}=2$ superconformal gauge theory, arising as effective field theory on a system of D-3-branes near an or…
On the Bound States of p- and (p+2)-Branes
E. Gava, K. S. Narain, M. H. Sarmadi
We study bound states of D-p-branes and D-(p+2)-branes. By switching on a large magnetic field F on the (p+2) brane, the problem is shown to admit a perturbative analysis in an exp…
D-branes and the Conifold Singularity
E. Gava, T. Jayaraman, K. S. Narain +1
We analyze in detail the description of type IIB theory on a Calabi-Yau three-fold near a conifold singularity in terms of intersecting D-branes. In particular we study the singula…
The Ring Structure of Chiral Operators for Minimal Models Coupled to 2D Gravity
M. H. Sarmadi
(Talk presented at the 1992 ICTP summer workshop in high energy physics and cosmology) The BRST cohomology ring for models coupled to gravity is discussed. In addition to t…
BRST cohomology ring in 2D gravity coupled to minimal models
H. Kanno, M. H. Sarmadi
The ring structure of Lian-Zuckerman states for minimal models coupled to gravity is shown to be where is the r…
