Cheung, Dersy and Schwartz report a transformer-based simplifier that reduces long spinor-helicity expressions and produces new compact five-point scalar and graviton amplitude expressions, alongside recovering the known five-gluon Parke–Taylor expression.

Original report: 2024-08-08Schwartz and Zhang report an analytical expression for the remaining elliptic sector of the next-to-next-to-leading-order energy-energy correlator in N = 4 super Yang–Mills theory, relating its curve to the sunrise integral and expressing the answer through iterated Eisenstein integrals.

Original report: 2026-10-07Matthew Schwartz reports a soft-collinear effective-theory factorization theorem for the C-parameter distribution near C = 3/4, computes the one-loop jet and soft ingredients, and presents matched next-to-leading-logarithmic plus next-to-leading-order predictions.
