Three-Pronged Strings and 1/4 BPS States in N=4 Super-Yang-Mills Theory
O. Bergman
We provide an explicit construction of 1/4 BPS states in four-dimensional N=4 Super-Yang-Mills theory with a gauge group SU(3). These states correspond to three-pronged strings con…
String Creation and Heterotic-Type I' Duality
O. Bergman, M. R. Gaberdiel, G. Lifschytz
The BPS spectrum of type I' string theory in a generic background is derived using the duality with the nine-dimensional heterotic string theory with Wilson lines. It is shown that…
Branes, Orientifolds and the Creation of Elementary Strings
O. Bergman, M. R. Gaberdiel, G. Lifschytz
The potential of a configuration of two Dirichlet branes for which the number of ND-directions is eight is determined. Depending on whether one of the branes is an anti-brane or a…
The Size of a Polymer of String-Bits: A Numerical Investigation
O. Bergman, C. B. Thorn
In string-bit models, string is described as a polymer of point-like constituents. We attempt to use string-bit ideas to investigate how the size of string is affected by string in…
A Non-Supersymmetric Open String Theory and S-Duality
Oren Bergman, Matthias R. Gaberdiel
A non-supersymmetric ten-dimensional open string theory is constructed as an orbifold of type I string theory, and as an orientifold of the bosonic type B theory. It is purely boso…
