1. Gravitational scattering in the high-energy limit / Liu, Zhengwen
Any gravitational scattering amplitude takes a remarkably simple factorized form at tree level in multi-Regge kinematics (MRK), where the produced particles are strongly ordered in rapidity. [...]

2. Bootstrapping solutions of scattering equations / Liu, Zhengwen ; Zhao, Xiaoran
The scattering equations are a set of algebraic equations connecting the kinematic space of massless particles and the moduli space of Riemann spheres with marked points. [...]

3. Multi-Regge kinematics and the scattering equations / Duhr, Claude ; Liu, Zhengwen
We study the solutions to the scattering equations in various quasi-multi-Regge regimes where the produced particles are ordered in rapidity. [...]

4. A note on connected formula for form factors / He, Song ; Liu, Zhengwen
In this note we study the connected prescription, originally derived from Witten’s twistor string theory, for tree-level form factors in N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory. [...]

5. Scattering equations, twistor-string formulas and double-soft limits in four dimensions / He, Song ; Liu, Zhengwen ; Wu, Jun-Bao
We study scattering equations and formulas for tree amplitudes of various theories in four dimensions, in terms of spinor helicity variables and on-shell superspace for supersymmetric theories. [...]
