چکیده
A bstract The singlet sector of the O ( N ) ϕ 4 -model in AdS at large- , gives rise to a dual conformal field theory on boundary which is deformation generalized free field. We identify and compute an three-point one-loop fish diagram that controls exact dimensions operator product coefficients (OPE) for all “double trace” operators as function renormalized -couplings. find space -coupling compact with bulk Landau pole. CFT unitary only interval negative couplings bounded by pole where lowest OPE coefficient diverges.

Non-unitarity in quantum affine Toda theory and perturbed conformal field theory
There has been some debate about the validity of quantum affine Toda field theory at imaginary coupling, owing to the non-unitarity of the action, and consequently of its usefulness as a model of perturbed conformal field theory. Drawing on our recent work, we investigate the two simplest affine Toda theories for which this is an issue – a (1) 2 and a (2) 2 . By investigating the S-matrices of ...
متن کاملOperads and Conformal Field Theory Lecture 1: Conformal Field Theory
Physicists have developed very advanced methods to compute such integrals. For example, the famous Feynman diagram technique allows us to compute the above integral for a rather particular function S(x), a small perturbation of a positive de nite quadratic form in R . Sometimes, elaborate techniques of physicists to compute simple things nd an amazing application to very general things in mathe...
متن کاملMinimal representations and reductive dual pairs in conformal field theory
A minimal representation of a simple non-compact Lie group is obtained by “quantizing” the minimal nilpotent coadjoint orbit of its Lie algebra. It provides context for Roger Howe’s notion of a reductive dual pair encountered recently in the description of global gauge symmetry of a (4-dimensional) conformal observable algebra. We give a pedagogical introduction to these notions and point out t...
متن کاملEnergy flux positivity and unitarity in conformal field theories.
We show that in most conformal field theories the condition of the energy flux positivity, proposed by Hofman and Maldacena, is equivalent to the absence of ghosts. At finite temperature and large energy and momenta, the two-point functions of the stress energy tensor develop lightlike poles. The residues of the poles can be computed, as long as the only spin-two conserved current, which appear...
