Conformal bootstrap near the edge
نویسندگان
چکیده
A bstract We propose a bootstrap program for CFTs near intersecting boundaries which form co-dimension 2 edge. describe the kinematical setup and show that bulk 1-pt functions bulk-edge 2-pt depend on non-trivial cross-ratio angle between boundaries. Using boundary OPE (BOE) with respect to each boundary, we derive two independent conformal block expansions these correlators. The matching of BOE leads crossing equation. analytically solve this equation in several simple cases, notably free field, where recover Feynman-diagrammatic results by Cardy.

Four-Fermion Theory and the Conformal Bootstrap
We employ the conformal bootstrap to re-examine the problem of finding the critical behavior of four-Fermion theory at its strong coupling fixed point. Existence of a solution of the bootstrap equations indicates self-consistency of the assumption that, in space-time dimensions less than four, the renormalization group flow of the coupling constant of a four-Fermion interaction has a nontrivial...
متن کاملConformal bootstrap for the BFKL Pomeron
We calculate the interaction vertex of three BFKL states including the bare triple BFKL Pomeron coupling and discuss its relation with the correlation functions in two-dimensional conformal field theory. We construct the operator algebra of the fields interpolating the BFKL states and show that in the multi-color limit the vertex satisfies the constraints imposed by the conformal bootstrap on t...

متن کاملOn the conformal bootstrap for SL(2,R)-WZNW models
Quantization of the SL(2,R)-WZNW model will be discussed from the point of view of the conformal bootstrap. Conformal blocks are defined from representations of affine sl(2) that are neither of highest nor lowest weight type. The general expression for the structure constants resp. three point functions is derived. Supplemented by a conjecture on the set of intermediate representations that con...
