Loop-Level Double Copy Relations from Forward Limits
Qu Cao, Song He, Yong Zhang +1
We study double copy relations for loop integrands in gauge theories and gravity based on their constructions from single cuts, which are in turn obtained from forward limits of lo…
Superstring amplitudes meet surfaceology
Qu Cao, Jin Dong, Song He +1
We reformulate tree-level amplitudes in open superstring theory (type-I) in terms of stringy Tr amplitudes with various kinematical shifts in the "curve-integral" formulatio…
Form factors from string amplitudes
Qu Cao
In this letter, we propose a stringy model for -point tree-level form factor with the off-shell operator in the scalar and gluon theories, from the bosonic string disk amplitude…
All-loop planar integrands in Yang-Mills theory from recursion
Qu Cao, Fan Zhu
In this letter, we generalize the recursion methods based on cut equations arXiv:2412.21027, originally developed for scalar theories, to gluons in pure Yang-Mills theory. In gauge…
