Shift operators and momentum-space conformal field theory
Francesca Caloro
A momentum-space approach to conformal field theory offers a new perspective on cosmological correlators and better reveals the underlying connections to scattering amplitudes. Thi…

-hypergeometric functions and creation operators for Feynman and Witten diagrams
Francesca Caloro, Paul McFadden
Both Feynman integrals and holographic Witten diagrams can be represented as multivariable hypergeometric functions of a class studied by Gel'fand, Kapranov & Zelevinsky known as G…

Shift operators from the simplex representation in momentum-space CFT
Francesca Caloro, Paul McFadden
We derive parametric integral representations for the general -point function of scalar operators in momentum-space conformal field theory. Recently, this was shown to be expres…
