On Symmetries of Some Massless 2D Field Theories
نویسنده
چکیده
We describe few aspects of the quantum symmetries of some massless two-dimensional field theories. We discuss their relations with recent proposals for the factorized scattering theories of the massless PCM1 and O(3)θ=π sigma models. We use these symmetries to propose massless factorized S-matrices for the su(2) sigma models with topological terms at any level, alias the PCMk models, and for the su(2)-coset massless flows.

Conformal Higher Spin Symmetries of 4 d Massless Supermultiplets and osp ( L , 2 M ) Invariant Equations in Generalized ( Super ) Space
Realization of the conformal higher spin symmetry on the 4d massless field supermultiplets is given. The self-conjugated supermultiplets, including the linearized N = 4 SYM theory, are considered in some detail. Duality between non-unitary field-theoretical representations and the unitary doubleton–type representations of the 4d conformal algebra su(2, 2) is formulated in terms of a Bogolyubov ...
متن کامل’t Hooft Anomaly Matching Conditions for Generalized Symmetries in 2D
The ’t Hooft anomaly matching conditions are a standard tool to study and test nonperturbative issues in quantum field theory. We give a new, simple proof of the anomaly matching conditions in 2D Poincarè invariant theories. We consider the case of invariance under a large class of generalized symmetries, which include abelian and non-abelian internal symmetries, space-time symmetries generated...
متن کاملInfinite Quantum Group Symmetry in 2d Quantum Field Theory
I describe how integrable quantum field theories in 2 spacetime dimensions are characterized by infinite dimensional quantum group symmetries, namely the q-deformations of affine Lie algebras, and their Yangian limit. These symmetries can provide a new non-perturbative formulation of the theories.
متن کاملMassless Higher Spins and Holography
We treat free large N superconformal field theories as holographic duals of higher spin (HS) gauge theories expanded around AdS spacetime with radius R. The HS gauge theories contain massless and light massive AdS fields. The HS current correlators are written in a crossing symmetric form including only exchange of other HS currents. This and other arguments point to the existence of a consiste...
متن کاملHeterotic effective action and duality symmetries revisited
The dimensional reduction of heterotic supergravity with gauge fields truncated to the Cartan subalgebra exhibits a continuous O(d, d+ 16;R) global symmetry, related to the O(d, d+16;Z) T-duality of heterotic strings on a d-torus. The O(d, d+16;R) symmetry is not present, however, if the supergravity reduction is done including the full set of E8×E8 or SO(32) gauge fields. We analyze which dual...
