New Factorizations of Yang-Mills Amplitudes
Alfredo Guevara, Yong Zhang
We propose a new factorization pattern for tree-level Yang-Mills (YM) amplitudes, where they decompose into a sum of gluings of two lower-point amplitudes by setting specific two-p…

On the New Factorizations of Yang-Mills Amplitudes
Yong Zhang
In this work, we prove the new factorization pattern for tree-level Yang-Mills (YM) amplitudes proposed in a companion paper. This pattern reveals a decomposition of amplitudes int…

One-loop Bern-Carrasco-Johansson Numerators on Quadratic Propagators from the Worldsheet
Jin Dong, Yao-Qi Zhang, Yong Zhang
We introduce a novel approach for deriving one-loop Bern-Carrasco-Johansson (BCJ) numerators and reveal the worldsheet origin of the one-loop double copy. Our work shows that expan…
