Description
I will present the current status in constructing a generic two-loop amplitude reduction algorithm within the HELAC computational framework. Following HELAC tree- and one-loop paradigm, we have completed the generation and validation of the two-loop amplitude-integrand as well as the algebraic reduction for Leading Color gg -> gg. I will present numerical construction and reduction results of the amplitude in d = 4 − 2ε dimensions. Following the OPP reduction approach, we express the amplitude in terms of Feynman integrals which are further reduced to master integrals through the IBP identities.
