Lightcone expansions of conformal blocks in closed form

A bstract 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 ℓ, they are composed of at most (ℓ + 1) Gaussian hypergeometric f...

Zusammenfassung:	A bstract 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 ℓ, they are composed of at most (ℓ + 1) Gaussian hypergeometric functions at each order.
