Description
Multiloop amplitudes are very important for the study of LHC physics. Given large number of Feynman diagrams, we need to consider the reduction to a small number of master integrals. Usually this is achieved by Integration-by-parts (IBP) relations, however, IBP computation is often very heavy. In this talk, we show the recent progress of IBP reduction, based on generalized unitarity and new mathematical method: computational algebraic geometry. Our package, AZURITE, which is designed to find master integrals will be presented.
