On Genera of Curves from High-loop Generalized Unitarity Cuts
Rijun Huang, Yang Zhang
Generalized unitarity cut of a Feynman diagram generates an algebraic system of polynomial equations. At high-loop levels, these equations may define a complex curve or a (hyper-)s…
The classification of two-loop integrand basis in pure four-dimension
Bo Feng, Rijun Huang
In this paper, we have made the attempt to classify the integrand basis of all two-loop diagrams in pure four-dimension space-time. Our classification includes the topology of two-…
Relations of loop partial amplitudes in gauge theory by Unitarity cut method
Bo Feng, Yin Jia, Rijun Huang
It is well known that under the color-decomposition, one-loop amplitude of gluons contains partial amplitudes of single and double trace structures, and particularly all partial am…
Cross Section Evaluation by Spinor Integration I: The massless case in 4D
Bo Feng, Rijun Huang, Yin Jia +2
To get the total cross section of one interaction from its amplitude , one needs to integrate over phase spaces of all out-going particles. Starting from t…
