Lightcone expansions of conformal blocks in closed form

High Energy Physics - Theory 2020-06-18 v2 Statistical Mechanics

Abstract

We present new closed-form expressions for 4-point scalar conformal blocks in the s- and t-channel lightcone expansions. Our formulae apply to intermediate operators of arbitrary spin in general dimensions. For physical spin \ell, they are composed of at most (+1)(\ell+1) Gaussian hypergeometric functions at each order.
