Three-Loop Five-Point CK-Dual Amplitudes and UV Structure in N=4 SYM and N=8 SUGRA
Zhiming Cai, Zeyu Li, Gang Yang +1
We construct the complete full-color three-loop five-point integrand of N=4 super-Yang--Mills theory in a representation that manifestly satisfies color--kinematics duality. Its do…
Dyeing form factors as amplitudes
Xinyue Li, Gang Yang, Guorui Zhu
The double copy of form factors has revealed a striking feature: poles that are spurious from the gauge-theory perspective become physical propagators in gravity. At the same time,…
AI for Pattern Hunter: Application in Wilson Loop of 2D Lattice Yang-Mills Theory
Zeyu Li, Guorui Zhu, Wenjie He +4
We employ the Transformer to learn patterns in two-dimensional lattice Yang-Mills theory. Specifically, we represent both Wilson loops and their expectation values as tokenized seq…
Double copy of form factors with multiple operator insertions
Xinyue Li, Gang Yang, Guorui Zhu
Extending the double copy of scattering amplitudes to more general physical quantities involving local gauge-invariant operators is a central open question. While progress has been…
Direct and Indirect Loop Equations in Lattice Yang-Mills Theory
Xizhe Liu, Gang Yang
The dynamics of Wilson loops are governed by an infinite set of Schwinger-Dyson equations and trace relations. In the context of the lattice positivity bootstrap, a central challen…
Bootstrapping SU(3) Lattice Yang-Mills Theory
Yuanhong Guo, Zeyu Li, Gang Yang +1
We apply the positivity bootstrap approach to SU(3) lattice Yang-Mills (YM) theory, extending previous studies of large N and SU(2) theories by incorporating multiple-trace Wilson…
