On Positive Geometry and Scattering Forms for Matter Particles
Aidan Herderschee, Song He, Fei Teng +1
We initiate the study of positive geometry and scattering forms for tree-level amplitudes with matter particles in the (anti-)fundamental representation of the color/flavor group.…

String Correlators: Recursive Expansion, Integration-by-Parts and Scattering Equations
Song He, Fei Teng, Yong Zhang
We further elaborate on the general construction proposed in arXiv:1812.03369, which connects, via tree-level double copy, massless string amplitudes with color-ordered QFT amplitu…

On the kinematic algebra for BCJ numerators beyond the MHV sector
Gang Chen, Henrik Johansson, Fei Teng +1
The duality between color and kinematics present in scattering amplitudes of Yang-Mills theory strongly suggest the existence of a hidden kinematic Lie algebra that controls the ga…
