Dangerous Liouville Wave — exactly marginal but non - conformal deformation
We give a non-trivially interacting field theory example of scale invariant but non-conformal field theory. The model is based on the exactly solvable Liouville field theory coupled with free scalars deformed by an exactly marginal operator. We show non-vanishing of the trace of the energy-momentum tensor by using the quantum Schwinger-Dyson equation for the Liouville field theory, which is a s...
متن کاملFermionic characters for graded parafermions
Fermionic-type character formulae are presented for charged irreducible modules of the graded parafermionic conformal field theory associated to the coset ôsp(1, 2)k/û(1). This is obtained by counting the weakly ordered ‘partitions’ subject to the graded Z̃k exclusion principle. The bosonic form of the characters is also presented.
متن کاملExactly marginal deformations of quiver gauge theories as seen from brane tilings
We study the relation between exactly marginal deformations in a large class of N = 1 superconformal quiver gauge theories described by brane tilings and the degrees of freedom in the corresponding 5brane systems. We show with the help of NSVZ exact β functions that there are generically d − 1 complex exactly marginal deformations of a gauge theory, where d is the perimeter of the corresponding...
متن کاملExactly Marginal Operators and Duality in Four Dimensional N = 1 Supersymmetric Gauge Theory
We show that manifolds of fixed points, which are generated by exactly marginal operators, are common in N=1 supersymmetric gauge theory. We present a unified and simple prescription for identifying these operators, using tools similar to those employed in two-dimensional N=2 supersymmetry. In particular we rely on the work of Shifman and Vainshtein relating the β-function of the gauge coupling...
متن کاملOn Renormalization Group Flows and Exactly Marginal Operators in Three Dimensions
As in two and four dimensions, supersymmetric conformal field theories in three dimensions can have exactly marginal operators. These are illustrated in a number of examples with N = 4 and N = 2 supersymmetry. The N = 2 theory of three chiral multiplets X,Y,Z and superpotential W = XY Z has an exactly marginal operator; N = 2 U(1) with one electron, which is mirror to this theory, has one also....
