The Large Hadron Collider (LHC) programs, along with upcoming collider projects, such as Electron Ion Collider (EIC), Circular Electron Positron Colliders (CEPC), are positioned to generate precise experimental data, necessitating accurate theoretical predictions. My research primarily centers on providing high-precision theoretical predictions for collider physics. In this presentation, I will go into some of the key aspects of my research journey during my PhD and Postdoc. This includes, for example, advancements in achieving complete four-loop splitting functions which are responcible for the evolution of N3LO pardon distribution functions (PDF), the evaluations of the peturbative matching coefficients for transverse-momentum-dependent PDFs (TMDPDFs) and fragmentation functions (TMDFFs) at the three-loop order, as well as applying Qt slicing method to get the first fully differential Drell-Yan production at N3LO in QCD. I will place emphasis on the physical motivation behind these developments and present the universal methodologies and mathematical structures employed in their evaluation. In the end of my talk, I will briefly talk about my future research proposals.

Tongzhi Yang, graduated from Zhejiang University in 2015 and obtained his Ph.D. at the same university in 2020 under the supervision of Mingxing Luo and Huaxing Zhu. He is currently a postdoctoral researcher at the University of Zurich, where he focuses on advancing high-precision predictions in perturbative Quantum Chromodynamics (pQCD). He shows particular interest in applying differential equation methods and modern integration-by-parts (IBP) reductions with finite-field techniques to compute various Wilson coefficients for collider processes or universal anomalous dimensions, such as beam functions, soft functions, as well as splitting functions.
