Moduli Space of Paired Punctures, Cyclohedra and Particle Pairs on a Circle
Zhenjie Li, Chi Zhang
In this paper, we study a new moduli space , which is obtained from by identifying pairs of punctures. We find that this spac…

Notes on Scattering Amplitudes as Differential Forms
Song He, Chi Zhang
Inspired by the idea of viewing amplitudes in SYM as differential forms on momentum twistor space, we introduce differential forms on the space of spinor variables, wh…

Scattering Forms, Worldsheet Forms and Amplitudes from Subspaces
Song He, Gongwang Yan, Chi Zhang +1
We present a general construction of two types of differential forms, based on any -dimensional subspace in the kinematic space of massless particles. The first type i…
