Correspondence between Solutions of Scattering Equations and Scattering Amplitudes in Four Dimensions
Yi-Jian Du, Fei Teng, Yong-Shi Wu
In this talk, we review our recent work on direct evaluation of tree-level MHV amplitudes by Cachazo-He-Yuan (CHY) formula. We also investigate the correspondence between solutions…
Leading order multi-soft behaviors of tree amplitudes in NLSM
Yi-Jian Du, Hui Luo
In this paper, we investigate multi-soft behaviors of tree amplitudes in nonlinear sigma model (NLSM). The leading behaviors of amplitudes with odd number of all-adjacent soft pion…
Direct Evaluation of -point single-trace MHV amplitudes in 4d Einstein-Yang-Mills theory using the CHY Formalism
Yi-Jian Du, Fei Teng, Yong-Shi Wu
In this paper we extend our techniques, developed in a previous paper (Du, etc, JHEP 05(2016)086) for direct evaluation of arbitrary -point tree-level MHV amplitudes in 4d Yang-…
Characterizing the solutions to scattering equations that support tree-level gauge/gravity amplitudes
Yi-Jian Du, Fei Teng, Yong-Shi Wu
In this paper we define, independent of theories, two discriminant matrices involving a solution to the scattering equations in four dimensions, the ranks of which are used to divi…
Explicit BCJ numerators of nonlinear sigma model
Yi-Jian Du, Chih-Hao Fu
In this paper, we investigate the color-kinematics duality in nonlinear sigma model (NLSM). We present explicit polynomial expressions for the kinematic numerators (BCJ numerators)…
CHY formula and MHV amplitudes
Yi-jian Du, Fei Teng, Yong-Shi Wu
In this paper, we study the relation between the Cachazo-He-Yuan (CHY) formula and the maximal-helicity-violating (MHV) amplitudes of Yang-Mills and gravity in four dimensions. We…
