Soft photon theorem in QCD with massless quarks
Yao Ma, George Sterman, Aniruddha Venkata
Working to all orders in dimensionally-regularized QCD, we study the radiation of a photon whose energy is much lower than that of external partons, but much larger than the masses…
The on-shell expansion: from Landau equations to the Newton polytope
Einan Gardi, Franz Herzog, Stephen Jones +2
We study the application of the method of regions to Feynman integrals with massless propagators contributing to off-shell Green's functions in Minkowski spacetime (with non-except…
Ground state baryons in the flux-tube three-body confinement model using Diffusion Monte Carlo
Yao Ma, Lu Meng, Yan-Ke Chen +1
We make a systematical diffusion Monte Carlo (DMC) calculation for all ground state baryons in two confinement scenarios, the pairwise confinement and the three-body flux-tube conf…
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…
An study of the channel scattering amplitude
Qu-Zhi Li, Yao Ma, Wen-Qi Niu +2
Extensive dynamical calculations are made in the study of channel low energy N scatterings, based on various phenomenological model inputs of left cuts at tree le…
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…
