Factorized lightcone expansion of conformal blocks

High Energy Physics - Theory 2021-05-20 v2 Statistical Mechanics

Abstract

We present a factorized decomposition of 4-point scalar conformal blocks near the lightcone, which applies to arbitrary intermediate spin and general spacetime dimensions. Then we discuss the systematic expansion in large intermediate spin and the resummations of the large-spin tails of Regge trajectories. The basic integrals for the Lorentzian inversion are given by Wilson functions.
