报告摘要：Quantum Chromodynamics (QCD) processes are ubiquitous at the LHC, and their precise understanding is crucial both for discovering new physics and for studying Standard Model itself. As LHC is preparing for the restart, unprecedented precision in theory prediction is called for, which requires the calculation of quantum radiative corrections. In recent years there have been enormous progress in advancing our abilities to perform high order calculation in perturbative quantum field theory, which ranged for example from effective field theory method, motivic structure of Feynman integral, and applied supersymmetry. We review how these ideas have led to better understanding of many aspects of QCD, including the structure function of proton, shower evolution of jet, and kinematics of the Higgs boson.
