Expansion of All Multitrace Tree Level EYM Amplitudes
Yi-Jian Du, Bo Feng, Fei Teng
In this paper, we investigate the expansion of tree level multitrace Einstein-Yang-Mills (EYM) amplitudes. First, we propose two types of recursive expansions of tree level EYM amp…
Understanding the Cancelation of Double Poles in the Pfaffian of CHY-formulism
Rijun Huang, Yi-Jian Du, Bo Feng
For a physical field theory, the tree-level amplitudes should possess only single poles. However, when computing amplitudes with Cachazo-He-Yuan (CHY) formulation, individual terms…
BCJ numerators from reduced Pfaffian
Yi-Jian Du, Fei Teng
By expanding the reduced Pfaffian in the tree level Cachazo-He-Yuan (CHY) integrands for Yang-Mills (YM) and nonlinear sigma model (NLSM), we can get the Bern-Carrasco-Johansson (B…
Expansion of Einstein-Yang-Mills Amplitude
Chih-Hao Fu, Yi-Jian Du, Rijun Huang +1
In this paper, we provide a thorough study on the expansion of single trace Einstein-Yang-Mills amplitudes into linear combination of color-ordered Yang-Mills amplitudes, from vari…
