摘要 |
The Standard Model (SM) of particle physics has been very successful for explaining the phenomenons we observed at particle colliders in the past decades. With all SM predicted particles found in the laboratory while many BSM (beyond Standard Model) predicted particles excluded from experimental data, high precision predictions of the SM has become a double edged sword. On one edge, it would help us make more reliable predictions of the SM. While on the other edge, it might help us to distinguish what can not be explained by the SM. In this talk, I will focus on the state-of-the-art fixed order (NNLO and above) QCD predictions of the SM. The general ingredients of higher order QCD calculation as well as modern tools for phenomenology study will be introduced. I will also explain the role of subtraction methods for QCD related processes and analyse in depth about how Antenna subtraction method works. |
