On the conformal anomaly of k-strings

چکیده
We discuss the long distance behaviour of the flux tube associated to baryon vertices and argue that, if the gauge system admits stable k-strings, the conformal field theory describing this string in the IR has conformal anomaly c = (d −2)σk/σ , where σk is the k-string tension and σ that of the fundamental representation. We check this result in a 3D Z4 gauge model at finite temperature, where a string effect directly related to c can be clearly identified.

The conformal anomaly of k-strings
Simple scaling properties of correlation functions of a confining gauge theory in d-dimensions lead to the conclusion that k-string dynamics is described, in the infrared limit, by a two-dimensional conformal field theory with conformal anomaly c = (d−2)σk/σ, where σk is the k-string tension and σ that of the fundamental representation. This result applies to any gauge theory with stable k-stri...
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...
متن کاملChiral non - critical strings ∗
It is shown that conformal matter with cL 6= cR can be consistently coupled to two-dimensional ‘frame’ gravity. The theory is quantized in conformal gauge, following David, and Distler and Kawai. There is no analogue of the c = 1 barrier found in nonchiral non-critical strings. A non-critical heterotic string is constructed—it has 744 states in its spectrum, transforming in the adjoint represen...
متن کاملChiral Deformations of Conformal Field Theories
We study general perturbations of two-dimensional conformal field theories by holomorphic fields. It is shown that the genus one partition function is controlled by a contact term (pre-Lie) algebra given in terms of the operator product expansion. These models have applications to vertex operator algebras, two-dimensional QCD, topological strings, holomorphic anomaly equations and modular prope...
متن کاملOperator product expansion of the energy momentum tensor in 2D conformal field theories on manifolds with boundary
Starting from the well-known expression for the trace anomaly we derive the T ·T operator product expansion of the energy-momentum tensor in 2D conformal theories defined in the upper halfplane without making use of the additional condition of no energy-momentum flux across the boundary. The OPE turns out to be the same as in the absence of the boundary. For this result it is crucial that the t...
