Chan-Paton Soliton Gauge States of Compatified Open String
نویسنده
چکیده
We study the mechanism of enhanced gauge symmetry of bosonic open string compatified on torus by analyzing the zero-norm soliton (nonzero winding of wilson line) gauge states in the spectrum. Unlike the closed string case, we find that the soliton gauge state exists only at massive levels. These soliton gauge states correspond to the existence of enhanced massive gauge symmetries with transformation parameters containing both Einstein and Yang-Mills indices. In the T-dual picture, these symmetries exist only at some discrete values of compatified radii when N D-branes are coincident. Typeset using REVTEX ∗e-mail: [email protected] 1

Soliton Gauge States and T-duality of Closed Bosonic String Compatified on Torus
We study soliton gauge states in the spectrum of bosonic string compatified on torus. The enhenced Kac-Moody gauge symmetry, and thus T-duality, is shown to be related to the existence of these soliton gauge states in some moduli points.

متن کاملHeterotic string.
Recent interest in superstring unified field theories has been sparked by the discovery of Green and Schwarz' that nonorientable (type I) open and closed superstrings with N = 1 supersymmetry are finite and free of anomalies if the gauge group is SO(32). Previously the only consistent, anomaly-free3 superstring theory was that of orientable (type II) N = 2 supersymmetric closed strings. The new...
متن کاملNon–orientable string one–loop corrections in the presence of a B field
We discuss the problem of noncommutative SO(N) gauge field theories from the string one–loop point of view. To this end we propose an expression for the string propagator on the boundary of the Möbius strip in the presence of a constant B field. We discuss in detail the problems related to its derivation. Then we use it to compute the one–loop corrections to two–, three– and four–gluon amplitud...
متن کاملNon-Abelian Gerbes from Strings on a Branched Space-Time
As superstring solitons that carry Neuveu–Schwarz charge can be described in terms of gerbes, one expects non-Abelian gerbes to appear e.g. in the exotic six-dimensional world-volume theories of coinciding NS5 branes. We consider open bosonic strings on a space-time that is branched in such a way that the B-field is provided with the same Lie algebra structure as the world-volume gauge field on...
متن کاملGauge/Gravity Correspondence and QCD
String theory has experienced a revolutionary period since around 1995. One of the most important discovery is the D-brane. It has opened up profound relationship between string theory and quantum field theory. Now we have come to the stage to consider realistic physics by applying the techniques developed in string theory to QCD. The purpose of this note is to provide a brief overview on the a...
