Interpolating String Field Theories
A minimal area problem imposing different length conditions on open and closed curves is shown to define a one parameter family of covariant open-closed quantum string field theories. These interpolate from a recently proposed factorizable open-closed theory up to an extended version of Witten’s open string field theory capable of incorporating on shell closed strings. The string diagrams of th...
متن کاملInterpolating State in String Field Theory
We derive an oscillator form for the Butterflies in terms of Sliver matrix S and its twisted version T as was already done for the Wedges in term of T . We write a General Squeezed state depending on a matrix U and we show in a compact way the interpolation between Identity state and the Sliver and between the Nothing state and the Sliver, growing in powers of T and S matrices, respectively, in...
متن کاملExact results on quantum field theories interpolating between pairs of conformal field theories
I review some recent results on conformal field theories in four dimensions and quantum field theories interpolating between conformal fixed points, supersymmetric and non-supersymmetric. The paper is structured in three parts: i) central charges, ii) anomalous dimensions and iii) quantum irreversibility. The family of theories, in general UV free, that interpolate between two conformal fixed p...
متن کاملApplication of Conformal Gauge Theories Derived from Field-String Duality
In this article I first give an abbreviated history of string theory and then describe the recently-conjectured fieldstring duality. This suggests a class of nonsupersymmetric gauge theories which are conformal (CGT) to leading order of 1/N and some of which may be conformal for finite N. These models are very rigid since the gauge group representations of not only the chiral fermions but also ...
متن کاملFeynman rules for string field theories with discrete target space
We derive a minimal set of Feynman rules for the loop amplitudes in unitary models of closed strings, whose target space is a simply laced (extended) Dynkin diagram. The string field Feynman graphs are composed of propagators, vertices (including tadpoles) of all topologies, and leg factors for the macroscopic loops. A vertex of given topology factorizes into a fusion coefficient for the matter...
