BCJ Numerators from Differential Operator of Multidimensional Residue
Gang Chen, Tianheng Wang
In previous works, we devised a differential operator for evaluating typical integrals appearing in the Cachazo-He-Yuan (CHY) forms and in this paper we further streamline this met…

A Combinatoric Shortcut to Evaluate CHY-forms
Gang Chen, Yeuk-Kwan E. Cheung, Tianheng Wang +1
In \cite{Chen:2016fgi} we proposed a differential operator for the evaluation of the multi-dimensional residues on isolated (zero-dimensional) poles.In this paper we discuss some n…
