The data collected so far led to the discovery and characterisati on of the Higgs boson and allowed important precision tests of the Standar d Model. In parallel to that\, continuous efforts are being made to shed l ight on possible New Physics up to the energy frontier. Accurate synergy b etween theory and experiment - and comparable precision on both sides - is key to foster discoveries. From the theory side\, the path to precision r uns through several directions. In several cases\, two-loop scattering amp litudes are the bottleneck. In this talk I will discuss ongoing efforts to wards integrand-level reduction of two-loop helicity amplitudes. First I w ill describe a method for extracting the coefficients of the reduction. I will elaborate on the advantages\, but also on the challenges\, of perform ing numerical computations of two-loop integrands in the context of dimens ional regularisation. Finally I will discuss work underway to develop a nu merical framework to achieve this goal.\n LOCATION:https://researchseminars.org/talk/NKUA-HEP/43/ END:VEVENT END:VCALENDAR
