"Monodromic vs holographic computation of Virasoro classical conformal blocks"

 

Abstract


We study holographic interpretation of classical conformal blocks in terms of particles propagating in AdS3 geometry. We consider n-point block with two heavy and n-2 light fields and describe the corresponding bulk configuration, which consists of n-3 particles propagating in the conical defect background produced by the heavy fields. We test the general picture in the case of five points. Using the monodromic approach we compute 5-point classical block and find the exact correspondence with the bulk world line action. The analysis relies upon the special perturbative procedure which treats n-point case as a deformation of (n-1)-pt case.
