A dispersive analysis of low energy pion photo- and electroproduction
Xiong-Hui Cao, Yao Ma
A dispersive representation based on unitarity and analyticity is used to study the low energy partial wave amplitudes. Final state interactio…

How does the state emerge from a naive matrix fit?
Yao Ma, Wen-Qi Niu, Yu-Fei Wang +1
We give a pedagogical analysis on matrix models describing the scattering amplitude, in channel at low energies. We show how the correct use of analyticity in the…

A Forest Formula to Subtract Infrared Singularities in Amplitudes for Wide-angle Scattering
Yao Ma
For any hard QCD amplitude with massless partons, infrared (IR) singularities arise from pinches in the complex planes of loop momenta, called pinch surfaces. To organize and study…
