In my talk I introduce the ColorFulNNLO method to calculate NNLO QCD corrections to any IR-safe observable in the case of three-jet production in electron-positron annihilation. Provided the ColorFulNNLO method is general it was implemented in a computer code called MCCSM (Monte Carlo for the ColorFulNNLO Subtraction Method). The capabilities of the code are demonstrated by calculating...

We present a phenomenological study of 4-jet production, calculated within high-energy factorization, including both contributions from single-parton and double-parton scattering. High-energy factorization causes a momentum inbalance in the final state, allowing for the description of observables at tree-level that would require next-to-leading order precision in collinear...

I will present the ALPHA collaboration's latest calculation of the Lambda parameter of QCD. Our method relies on experimental inputs of low energy quantities like pseudo-scalar decay constants only. The scale dependence of a coupling in a finite volume renormalization scheme is computed non-perturbatively in lattice QCD over many orders of magnitude in the energy scale. At high...
57. Progress in constructing epsilon form of differential equations for master integrals with Fuchsia

We review Fuchsia: an open-source tool for constructing epsilon form of differential equations for Feynman master integrals based on the Lee algorithm. We show several examples of its application to various problems in Quantum Field Theory which require virtual and real momenta integration. We discuss current status of the project and possible extensions in the future.
