Deskripsi
Abstract In this manuscript, we report the outcome of the topical workshop: paving the way to alternative NNLO strategies ( https://indico.ific.uv.es/e/WorkStop-ThinkStart_3.0 ), by presenting a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies to deal with infrared and ultraviolet singularities in quantum field theories. A special emphasis is devoted to the local cancellation of these singularities, which can enhance the efficiency of computations and lead to discover novel mathematical properties in quantum field theories.
