All-order celestial OPE from on-shell recursion
Lecheng Ren, Anders Schreiber, Atul Sharma +1
We determine tree level, all-order celestial operator product expansions (OPEs) of gluons and gravitons in the maximally helicity violating (MHV) sector. We start by obtaining the…
Symbol Alphabets from Plabic Graphs III: n=9
Jorge Mago, Anders Schreiber, Marcus Spradlin +2
Symbol alphabets of n-particle amplitudes in N=4 super-Yang-Mills theory are known to contain certain cluster variables of Gr(4,n) as well as certain algebraic functions of cluster…
Symbol Alphabets from Plabic Graphs II: Rational Letters
Jorge Mago, Anders Schreiber, Marcus Spradlin +2
Symbol alphabets of n-particle amplitudes in N=4 super-Yang-Mills theory are known to contain certain cluster variables of Gr(4,n) as well as certain algebraic functions of cluster…

A Note on One-loop Cluster Adjacency in N = 4 SYM
Jorge Mago, Anders Schreiber, Marcus Spradlin +1
We study cluster adjacency conjectures for amplitudes in maximally supersymmetric Yang-Mills theory. We show that the n-point one-loop NMHV ratio function satisfies Steinmann clust…
Yangian Invariants and Cluster Adjacency in N=4 Yang-Mills
Jorge Mago, Anders Schreiber, Marcus Spradlin +1
We conjecture that every rational Yangian invariant in N=4 SYM theory satisfies a recently introduced notion of cluster adjacency. We provide evidence for this conjecture by using…
Celestial Amplitudes: Conformal Partial Waves and Soft Limits
Dhritiman Nandan, Anders Schreiber, Anastasia Volovich +1
Massless scattering amplitudes in four-dimensional Minkowski spacetime can be Mellin transformed to correlation functions on the celestial sphere at null infinity called celestial…
Tree-level gluon amplitudes on the celestial sphere
Anders Schreiber, Anastasia Volovich, Michael Zlotnikov
Pasterski, Shao and Strominger have recently proposed that massless scattering amplitudes can be mapped to correlators on the celestial sphere at infinity via a Mellin transform. W…
Chiral squaring and KLT relations
Anders Schreiber
We demonstrate that amplitudes based on matter supermultiplets can be combined to provide amplitudes of vector supermultiplets by means of KLT relations. In practice we do this by…
