The rational Part of QCD Amplitude I: the General Formalism
rational Part QCD Amplitude the General Formalism
2018/4/20
A general formalism for computing only the rational part of the one-loop QCD amplitude is developed. Starting from the Feynman integral representation of the one-loop amplitude, we use tensor re- duct...
The Rational Part of QCD Amplitude II: the Five-Gluon
Rational Part QCD Amplitude Five-Gluon
2018/4/20
The rational part of the 5-gluon one-loop amplitude is computed by using the newly developed method for computing the rational part directly from Feynman integrals. We found complete agreement with th...
The rational part of the 6-gluon one-loop amplitude with scalar cir- culating in the loop is computed by using the newly developed method for computing the rational part directly from Feynman integral...
