Comments on spinning OPE blocks in AdS\(_{3}\)/CFT\(_{2}\)
We extend the work of \cite{Ferrara:1971vh},\cite{Ferrara:1973vz}, to obtain an integral expression of OPE blocks for spinning primaries in CFT\(_{2}\). We observe, when the OPE blocks are made out of conserved spinning primaries, the integral becomes a product of two copies of weighted AdS\(_{2}\)...

Zusammenfassung: | We extend the work of \cite{Ferrara:1971vh},\cite{Ferrara:1973vz}, to obtain an integral expression of OPE blocks for spinning primaries in CFT\(_{2}\). We observe, when the OPE blocks are made out of conserved spinning primaries, the integral becomes a product of two copies of weighted AdS\(_{2}\) fields, smeared along geodesics. In this way, conserved current OPE blocks in CFT\(_{2}\) have a different representation in terms of AdS\(_{2}\) geodesic operators, in stead of viewing them as AdS\(_{3}\) geodesic operators. We also show, how this representation can be related to AdS\(_{3}\) massless higher spin fields through HKLL bulk field reconstruction. Using this picture, we consistently obtain the closed form expression of four point spinning conformal block as a product of two AdS\(_{2}\) Geodesic Witten diagrams. |
