Gauge-field mixing in supersymmetric cosmic string theories
نویسندگان
چکیده
In this paper, following a stream of investigation of supersymetric gauge theories with cosmic string solutions, we contemplate the possibility of building up a superconducting cosmic string with a gauge-field mixing in conection with to a U(1) × U(1)′symmetry. Both spontaneous breakings, of gauge and supersymmetry, are thoroughly analysed and the fermion zero-modes are worked out. The rôle of the gauge-field mixing parameter is elucidated in conection with the string configuration. [email protected] [email protected] [email protected] 1

متن کاملCosmic Strings in Supergravity
It is pointed out that various types of cosmic string solutions that exist in nonsupersymmetric and globally supersymmetric theories, such as D-type gauge strings, F-type global and gauge strings, and superconducting Witten strings, also exist in supergravity models. When the D term and superpotential satisfy some simple conditions allowing the determination of a set of vacuum states with nontr...
متن کاملUV/IR Mixing via Closed Strings and Tachyonic Instabilities
We discuss UV/IR mixing effects in non-supersymmetric noncommutative U(N) gauge theories. We show that the singular (nonplanar) terms in the 2and 3-point functions, namely the poles and the logarithms, can be obtained from a manifestly gauge invariant effective action. The action, which involves open Wilson line operators, can be derived from closed strings exchange between two stacks of Dbrane...
متن کاملBranes and N=1 Duality in String Theory
We propose a construction of dual pairs in four dimensional N=1 supersymmetric Yang-Mills theory using branes in type IIA string theory. Supersymmetric gauge theories invariant under eight or sixteen supercharges (e.g. N=2 and N=4 supersymmetric Yang-Mills theories in four dimensions, respectively) have been intensively studied in the last few years. Many of the diverse strong coupling phenomen...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
