Deformed Algebras in the Celestial CFT
Jorge Mago, Lecheng Ren, Akshay Yelleshpur Srikant +1
We compute the modification of the algebra of soft graviton, gluon and scalar currents in the celestial CFT due to non-minimal couplings. We find that the Jacobi ide…
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…
Weak Separation, Positivity and Extremal Yangian Invariants
Luke Lippstreu, Jorge Mago, Marcus Spradlin +1
We classify all positive n-particle N^kMHV Yangian invariants in N=4 Yang-Mills theory with n=5k, which we call extremal because none exist for n>5k. We show that this problem is e…
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…
