报告摘要：Monte-Carlo event generators are indispensable tools in high-energy physics, providing the bridge between fundamental theory and experimentally measurable observables. A central component of these generators is the parton shower, whose accuracy critically affects the reliability of collider predictions. In this talk, I will review recent advances in parton-shower technology, with a particular focus on efforts to consistently incorporate next-to-leading-order (NLO) corrections into shower kernels. I will then discuss the antenna-shower framework and illustrate its advantages in capturing QCD radiation patterns. Building on these developments, I will present a new method that enables next-to-next-to-leading-order (NNLO) precision directly from shower algorithms. This approach opens a promising path toward systematically improving the perturbative accuracy of event generators for current and future collider experiments.
