  • Closed-form expression for cross-channel conformal blocks near the lightcone

    Wenliang Li

    … Based on the nonperturbative pole structure in spin of Lorentzian inversion, we propose the natural basis functions for cross-channel conformal blocks. … In this new basis, we find a closed-form expression for crossed conformal blocks in terms of the Kampe de Feriet function, which applies to intermediate operators of arbitrary spin in general dimensions. … Our results for the lightcone limit also shed light on the complete analytic structure of conformal blocks in the lightcone expansion. …
