主　　题：Feynman integrals reduction five-light-parton scattering 

摘      要：We reduce all the most complicated Feynman integrals in two-loop five-light-parton scattering amplitudes to basic master integrals,while other integrals can be reduced even *** results are expressed as systems of linear relations in the block-triangular form,very efficient for numerical *** results are crucial for complete next-to-next-to-leading order quantum chromodynamics calculations for three-jet,photon,and/or hadron production at hadron *** determine the block-triangular relations,we develop an efficient and general method,which may provide a practical solution to the bottleneck problem of reducing multiloop multiscale integrals.
